futur antérieur

The future perfect is a verb form or construction used to describe an event that is expected or planned to happen before a time of reference in the future, such as ''will have finished'' in the English sentence "I will have finished by tomorrow." It is a grammatical combination of the future tense, or other marking of future time, and the perfect, a grammatical aspect that views an event as prior and completed.

English

In English, the future perfect construction consists of a future construction such as the auxiliary verb ''will'' (or ''shall'') or the going-to future and the perfect infinitive of the main verb (which consists of the infinitive of the auxiliary verb ''have'' and the past participle of the main verb). This parallels the construction of the "normal" future verb forms combining the same first components with the plain infinitive (e.g. ''She will fall'' / ''She is going to fall''). For example:
* She will have fallen asleep by the time we get home.
* I shall have gone by then.
* Will you have finished when I get back?

The auxiliary is commonly contracted to ''ll'' in speech and often in writing, and the first part of the perfect infinitive is commonly contracted to ''ve'' in speech: see English auxiliaries and contractions. The negative form is made with ''will not'' or ''shall not''; these have their own contractions ''won't'' and ''shan't''. Some examples:
*Ill have made the dinner by 6 PM.
* He won't have done (''or'' will not have done) it by this evening.
* Won't you have finished by Thursday? (''or'' Will you not have finished by Thursday?)

Most commonly the future perfect is used with a time marker that indicates ''by when'' (i.e., prior to what point in time) the event is to occur, as in the previous examples. However, it is also possible for it to be accompanied by a marker of the retrospective time of occurrence, as in "I will have done it on the previous Tuesday". This is in contrast to the present perfect, which is not normally used with a marker of past time: one would not say "I have done it last Tuesday", since the inclusion of the past time marker ''last Tuesday'' would entail the use of the simple past rather than the present perfect.

The English future perfect places the action relative only to the absolute future reference point, without specifying the location in time relative to the present. In most cases the action will be in the future relative to the present, but this is not necessarily the case: for example, "If it rains tomorrow, we will have worked in vain yesterday."

The future perfect construction with ''will'' (like other constructions with that auxiliary) is sometimes used to refer to a confidently assumed present situation rather than a future situation, as in "He will have woken up by now."

The time of perspective of the English future perfect can be shifted from the present to the past by replacing ''will'' with its past tense form ''would'', thus effectively creating a "past of the future of the past" construction in which the indicated event or situation occurs before a time that occurs after the past time of perspective: ''In 1982, I knew that by 1986 I would have already gone to prison''. This construction is identical to the English conditional perfect construction.

An obsolete term found in old grammars for the English future perfect is the "second future tense."

Spanish

In Spanish, the future perfect is formed as this:

The future of ''haber'' is formed by the future stem ''habr'' + the endings ''-é'', ''-ás'', ''-á'', ''-emos'', ''-éis'', ''-án''. The past participle of a verb is formed by adding the endings ''-ado'' and ''-ido'' to ''ar'' and ''er''/''ir'' verbs, respectively. However, there are a few irregular participles such as these:

:''abrir: abierto''
:''cubrir: cubierto''
:''decir: dicho''
:''escribir: escrito''
:''freír: frito''
:''hacer: hecho''
:''morir: muerto''
:''poner: puesto''
:''ver: visto''
:''volver: vuelto''

Verbs within verbs also have the same participle, for example, ''predecir'' ("to predict') would be ''predicho''; ''suponer'' ("to suppose") would be ''supuesto''. Also, ''satisfacer'' ("to satisfy") is close to ''hacer'' ("to do") in that the past participle is ''satisfecho''.

To make the tense negative, ''no'' is simply added before the form of ''haber'': ''yo no habré hablado''. For use with reflexive verbs, the reflexive pronoun is before the form of ''haber'': from ''bañarse'' ("to take a bath"), ''yo me habré bañado''; negative: ''yo no me habré bañado''.

Portuguese

In Portuguese, the future perfect is formed like in to Spanish:
: subject + future of or + past participle

: ''eu haverei falado'' ("I will have spoken")
: ''eu terei falado'' ("I will have spoken")

The future of ''ter'' is formed by the future stem ''ter'' + the endings ''-ei, -ás, -á, -emos, -eis, -ão'' (the 2nd person plural form ''tereis'' is, however, archaic). The past participle of a verb is formed in turn by adding the endings -ado and -ido to the stems of ''-ar'' and ''-er/-ir'' verbs, respectively. However, there are a few irregular participles such as these:

:''abrir: aberto''
:''cobrir: coberto''
:''dizer: dito''
:''escrever: escrito''
:''fazer: feito''
:''ganhar: ganho''
:''gastar: gasto''
:''pagar: pago''
:''pôr: posto''
:''ver: visto''
:''vir: vindo''

Several verbs that are derived from the irregular verbs above form their past participle similarly like the past participle of ''predizer'' ("to predict') is ''predito''; for ''supor'' ("to suppose"), it would be ''suposto'', and ''satisfazer'' ("to satisfy"), which is derived from ''fazer'' ("to do"), has the past participle '' satisfeito''.

To make the sentence negative, ''não'' is simply added before the conjugated form of ''ter'': ''eu não terei falado''. When using the future perfect with oblique pronouns, European Portuguese and formal written Brazilian Portuguese use mesoclisis of the pronoun in the affirmative form and place the pronoun before the auxiliary verb in the negative form:

: ''Eu tê-lo-ei visto'' ("I will have seen him")
: ''Eu não o terei visto'' ("I will not have seen him")

: ''Eles ter-me-ão visto'' ( "They will have seen me")
: ''Eles não me terão visto'' ("They will not have seen me")

Informal Brazilian Portuguese usually places ''stressed'' pronouns such as ''me, te, se, nos'' and ''lhe/lhes'' between the conjugated form of ''ter'' and the past participle: ''eles terão me visto''; in the negative form, both ''eles não terão me visto'' and ''eles não me terão visto'' are possible, but the latter is more formal and preferred in the written language.

Unstressed pronouns like ''o'' and ''a'' are normally placed before the conjugated form of ''ter'': ''eu o terei visto''; ''eu não o terei visto''.

French

The French future perfect, called ''futur antérieur'', is formed like in Spanish:

However, verbs that use ''être'' in the past ("House of Être" verbs, reflexive verbs) use ''être'' to form the present perfect. For example, ''je serai venu(e)'' uses the future of ''être'' because of the action verb, ''venir'' (to come), which uses ''être'' in the past.

To form the future form of the auxiliary verbs, the future stem is used, and the endings ''-ai'', ''-as'', ''-a'', ''-ons'', ''-ez'', ''-ont'' are added. Both ''avoir'' and ''être'' have irregular future stems, but with the exception of ''-re'' verbs, most verbs use the infinitive as the future stem (''je parler-ai'', I will speak), the future stem of ''avoir'' "is" ''aur-'', and the future stem of ''être'' is ''ser-''.

To form the past participle in French, one usually adds ''-é'', ''-i'', and ''-u'' to the roots of ''-er'', ''-ir'', and ''-re'' verbs, respectively. However, there are many exceptions to this rule, including these commonly used ones (and all of their related verbs):
*''faire: fait''
*''mettre: mis''
*''ouvrir: ouvert''
*''prendre: pris''
*''venir: venu''

Verbs related to ''mettre'' ("to put"): ''promettre'' ("to promise"); to ''ouvrir'': ''offrir'' ("to offer"), ''souffrir'' ("to suffer"); to ''prendre'' ("to take"): ''apprendre'' ("to learn"), ''comprendre'' ("to understand"); to ''venir'' ("to come"): ''revenir'' ("to come again"), ''devenir'' ("to become").

When using ''être'' as the auxiliary verb, one must make sure that the past participle agrees with the subject: ''je serai venu'' ("I asc.will have come"), ''je serai venue'' ("I em.will have come"); ''nous serons venus'' ("We asc. or mixedwill have come"), ''nous serons venues'' ('We em.will have come"). Verbs using ''avoir'' do not need agreement.

To make this form negative, one simply adds ''ne'' (''n'' if before a vowel) before the auxiliary verb and ''pas'' after it: ''je n'aurai pas parlé''; ''je ne serai pas venu''. For reflexive verbs, one puts the reflexive pronoun before the auxiliary verb: from ''se baigner'' ("to take a bath"), ''je me serai baigné''; negative: ''je ne me serai pas baigné''.

German

The future perfect in German (called ''"Futur II"'', ''"Vorzukunft"'' or ''"vollendete Zukunft"'') is formed like it is in English, by taking the simple future of the past infinitive. For that, the simple future of the auxiliary ''sein'' (= ''ich werde sein, du wirst sein'' etc.) or ''haben'' (= ''ich werde haben, du wirst haben'', etc.) is used to enclose the past participle of the relevant verb (''ich werde gemacht haben, du wirst gemacht haben'', etc.):

::*''Ich werde etwas geschrieben haben.''
:::"I will have written something."
::*''Morgen um diese Uhrzeit werden wir bereits die Mathe-Prüfung gehabt haben''.
:::"Tomorrow at the same time we already will have had the math exam."
::*''Es wird ihm gelungen sein.''
:::"He will have succeeded."
::*''Wir werden angekommen sein.''
:::"We will have arrived."

Dutch

The Dutch future perfect tense is very similar to the German future perfect tense. It is formed by using the verb ''zullen'' ("shall") and then placing the past participle and ''hebben'' ("to have") or ''zijn'' ("to be") after it:
::''Ik zal iets geschreven hebben''.
::"I shall something written have."
::"I will have written something."

Afrikaans

The Afrikaans future perfect tense is very similar to the Dutch future perfect tense. It is formed by using the verb ''sal'' ("shall") followed by the past participle and ''het'' (conjugated form of the verb ''hê''):

::''Ek sal iets geskryf (*) het''.
::"I shall something written have."
::"I will have written something."

(*) Unlike in Dutch, almost all past participles in Afrikaans are regular (with a few exceptions like ''gehad'' and ''gedag''). The Dutch strong participles are, however, sometimes preserved in Afrikaans when the participles are used as adjectives:

:: Dutch: ''Ik zal een brief geschreven hebben''
:: Afrikaans: ''Ek sal 'n brief geskryf het''
:: English: "I will have written a letter"

::Dutch: '' een geschreven brief''
::Afrikaans: '' 'n Geskrewe brief''
::English: "a written letter"

Catalan

In Catalan, the future perfect is formed as this:

The future of ''haver'' is formed by the future stem ''haver'' + the endings ''-é'', ''-às'', ''-à'', ''-em'', ''-eu'', ''-an''. The past participle of a verb is formed by adding the endings ''-at'', ''-ut'' and ''-it'' to ''ar'', ''er'', ''ir'' verbs, respectively. However, there are a few irregular participles such as these:

:''caldre: calgut''
:''córrer: corregut''
:''creure: cregut''
:''dir: dit''
:''dur: dut''
:''empènyer: empès''
:''entendre: entès''
:''escriure: escrit''
:''fer: fet''
:''fondre: fos''
:''haver: hagut''
:''imprimir: imprès''
:''morir: mort''
:''obrir: obert''
:''prendre: pres''
:''resoldre: resolt''
:''riure: rigut''
:''treure: tret''
:''valer: valgut''
:''venir: vingut''
:''viure: viscut''

To make the tense negative, ''no'' is simply added before the form of ''haver'': ''jo no hauré parlat''. For use with reflexive verbs, the reflexive pronoun is before the form of ''haver'': from ''banyar-se'' ("to take a bath"), ''jo m'hauré banyat''; negative: ''jo no m'hauré banyat''.

Greek

In Modern Greek, the future perfect is formed with the future particle θα ''tha'', an auxiliary verb (έχω or είμαι ''écho, íme'' "to have" or "to be"), and the infinitive or participle.
*"I will have finished by then"
*:Θα έχω τελειώσει ... ("have" + infinitive)
*:Tha écho teliósi ...
*"I will be hired by then"
*:θα είμαι προσληφθείς ... ("be" + participle)
*:''Tha ime proslipthis''

In Ancient Greek, the future perfect of the active voice is most commonly formed periphrastically by combining the future tense of the verb "to be" with the perfect active participle, for example "I shall have loosed". In the middle and passive voice, the periphrastic construction is also very common, but a synthetic construction is found as well, by adding the endings of the future tense to the perfect stem, for example "I shall have been loosed". The synthetic construction is rare, and found only with a few verbs.

Latin

In Latin conjugation, the active future perfect is formed by suffixing the future forms of ''esse'' "to be" to the perfect stem of the verb. An exception is the active indicative third person plural, where the suffix is ''-erint'' instead of the expected ''-erunt''. E.g. ''amaverint'', not ''**amaverunt''.

The passive future perfect is formed using the passive perfect participle and the future of ''esse''. Note that the participle is inflected like a normal adjective, i.e. it agrees grammatically with the subject.

Italian

The future perfect is used to say that something will happen in the future but before the time of the main sentence. It is called ''futuro anteriore'' and is formed by using the appropriate auxiliary verb "to be" (''essere'') or "to have" (''avere'') in the future simple tense followed by the past participle:

:''Io avrò mangiato'' ("I will have eaten")
:''Io sarò andato/a'' ("I will have gone")

It is also used for to express doubt about the past like the English use of "must have":

''Carlo e sua moglie non si parlano più: avranno litigato'' ("Carlo and his wife are no longer talking: they must have quarrelled")

To translate "By the time/When I have done this, you will have done that", Italian uses the double future: ''Quando io avrò fatto questo, tu avrai fatto quello''.

Romanian

The Romanian ''viitor anterior'' is used to refer to an action that will happen (and finish) before another future action. It is formed by the future simple tense of ''a fi'' (to be) followed by the participle of the verb.

:''Eu voi fi ajuns acasă deja la ora 11.'' ("I will have arrived home already at 11 o'clock.")

Croatian

In Croatian, the future perfect is known as future II (''futur drugi'') or future exact (''futur egzaktni''), and is the pre-future verb tense. In modern usage, it appears to denote future action in temporal clauses, but not its sequence relative to the action in the main clause. In conditional, relative, comparative and some other types of clauses it signifies priority and concurrency (a pre-future action that must take place in order for another action to take place), where future I means future subsequence:
* ''Ako budeš gledao koncert, vidjet ćeš me na pozornici.'' (If you watch the concert, you'll see me on the stage.)

The tense is formed from the present perfect form of the auxiliary verb ''to be'' (I: ''budem'' You: ''budeš'' He/She:''bude'' We:''budemo'' You:''budete'' They:''budu)'', and the so-called active verbal adjective. Modern grammars seem to agree that the future perfect is mostly formed from imperfective verbs, whereas its use from perfective verbs is replaceable by the present tense.

In the Kajkavian dialect, future perfect verbal forms are used instead of the nonexistent future tense forms of the standard Croatian language.

Serbian

It is usually restricted to conditional clauses. It is formed from a conjugated form of auxiliary verb ''biti'' ("to be") in the imperfective aspect plus past participle, which can be in any aspect and is conjugated for gender and number. Since Serbo-Croatian has a developed aspect system this tense is considered redundant.

:''Kad budem pojeo...'' ("When I will have eaten...")
:''Nakon što budeš gotov...'' ("After you will have been done...")
