infixes

An infix is an affix inserted inside a word stem (an existing word or the core of a family of words). It contrasts with ''adfix,'' a rare term for an affix attached to the outside of a stem, such as a prefix or suffix.

When marking text for interlinear glossing, most affixes are separated with a hyphen, but infixes are separated with .

English

English has almost no true infixes (as opposed to tmesis) and those it does have are marginal. A few are heard in colloquial speech, and a few more are found in technical terminology.

Colloquialisms

None of the following are recognized in standard English.
* The infix or is characteristic of hip-hop slang, for example ''h-iz-ouse'' for ''house'' and ''sh-izn-it'' for ''shit.''
* The infix (or "Homeric infix," after Homer Simpson), whose location in the word is described in , gives a word an ironic pseudo-sophistication, as in ''sophisti-ma-cated (sophisticated), saxo-ma-phone,'' (saxophone) and ''edu-ma-cation.'' (education) This exists as a slang phenomenon.
*Infixes also occur in some language games.
* The use of ' expletive infixes' such as ''-fucking-'' and ''-bloody-'', which are words rather than affixes, is known as tmesis.
* A /ə/ infix can split a word-initial consonant cluster to add emphasis to the word. For example, "I didn't say paint the room red, I said black... ə'læk Capische?", or the most commonly used word being an infixed version of the word "please", "Oh ə'liz give me a break".

Indo-European nasal infix

The present tense of some Proto-Indo-European verbs, in the case of a certain number of roots, adds a nasal infix (''m'', ''n'') to the basic root. The stems of the other tenses have the root without the infix, and thus these verbs are called ''nasal-presents''. This phenomenon is inherited, and preserved to varying degrees, by some early daughter languages such as Sanskrit, Ancient Greek, Latin language, etc.

* Sanskrit exhibits the greatest transparency of this feature amongst the Indo-European languages, with the phenomenon manifesting in three of the ten traditional verb classes, where the infix is higher-grade and accent-bearing in the strong forms, and reduced-grade in the weak forms. For example, , 'join' has 's/he joins' ↔ , 'they join'.

* Latin present "I win" (cf. perfect passive participle "conquered")
* Ancient Greek (also with suffix) "I take" (cf. aorist "I took")

Spanish

In Nicaraguan, Costa Rican, and Honduran Spanish, the Spanish diminutive affix becomes an infix in names: → (cf. standard ); → ; → .

Arabic

Arabic uses a common infix, for Form VIII verbs, usually a reflexive of Form I. It is placed after the first consonant of the root; an epenthetic ''i-'' prefix is also added, since words cannot begin with a consonant cluster. An example is "he worked hard", from "he strove". (The words and are nouns derived from these two verbs.)

Austronesian and Austroasiatic languages

Infixes are common in Austronesian and Austroasiatic languages. For example, in Tagalog, a grammatical form similar to the active voice is formed by adding the infix near the beginning of a verb. The most common infix is used to make an intentional verb, as in '', meaning ‘ruined’ (from ‘’, an adjective meaning ‘worn-out’); '’, meaning ‘stoned’ (from ‘’, ‘stone’); and '’, meaning ‘used’. Tagalog has borrowed the English word ''graduate'' as a verb; to say "I graduated" a speaker uses the derived form .

Khmer, an Austroasiatic language, has seven different infixes. They include the nominalizing infix , which derives 'speed' from 'fast' and ' trial' from 'to test, to haunt', or the agentive deriving 'watchman' from 'to watch'. These elements are no longer productive, and occur crystallized in words inherited from Old Khmer.

In Malay and Indonesian, there are three infixes (''sisipan''), , , and . All infixes are no longer productive and cannot be used to derive new words.
Examples include:
* The word 'gembung' (variant of 'kembung') means "bloated", while 'gelembung' means "bubble"'.
* The word 'cerlang' means "luminous", while 'cemerlang' means "brilliant"'.
* The word 'gigi' means "tooth", while 'gerigi' means "serration"'.

Seri

In Seri, some verbs form the plural stem with infixation of after the first vowel of the root; compare the singular stem ''ic'' 'plant (verb)' with the plural stem ''itóoc''. Examples: ''itíc'' 'did s/he plant it?' and ''ititóoc'' 'did they sow it?'.

Similar processes

Tmesis, the use of a lexical word rather than an affix, is sometimes considered a type of infixation. These are the so-called "expletive infixes", as in ''abso-bloody-lutely''. Since these are not affixes, they are commonly disqualified from being considered infixes.

Sequences of adfixes (prefixes or suffixes) do not result in infixes: an infix must be internal to a word stem. Thus, the word ''originally,'' formed by adding the suffix ''-ly'' to ''original,'' does not turn the suffix ''-al'' into an infix. There is simply a sequence of two suffixes, ''origin-al-ly.'' In order for ''-al-'' to be considered an infix, it would have to have been inserted in the non-existent word ''*originly.'' The "infixes" in the tradition of Bantu linguistics are often sequences of prefixes of this type, though there may be debate over specific cases.

The Semitic languages have a form of ''ablaut'' (changing the vowels within words, as in English ''sing, sang, sung, song)'' that is sometimes called infixation, as the vowels are placed between the consonants of the root. However, this interdigitation of a discontinuous root with a discontinuous affix is more often called '' transfixation''.

An ''interfix'' joins a compound word, as in ''speed-o-meter''.

Glossing

When glossing, it is conventional to set off infixes with , rather than the hyphens used to set off prefixes and suffixes:
:''shit, saxophone, picoline''

Compare:
:''origin-al-ly''
which contains the suffix ''-ly'' added to the word ''original,'' which is itself formed by adding the suffix ''-al'' to the root ''origin.''
