Flat adverb

In English grammar, a flat adverb, bare adverb, or simple adverb is an adverb that has the same form as the corresponding adjective,Garner's Modern American Usage
p. 897 so it usually does not end in ''-ly'', e.g. "drive ''slow''", "drive ''fast''", "dress ''smart''", etc. The term includes words that naturally end in -ly in both forms, e.g. "drive ''friendly''". Flat adverbs were once quite common but have been largely replaced by their ''-ly'' counterparts. In the 18th century, grammarians believed flat adverbs to be adjectives, and insisted that adverbs needed to end in ''-ly''. According to the Merriam-Webster Dictionary, "It's these grammarians we have to thank for ... the sad lack of flat adverbs today"."Drive Safe: In Praise of Flat Adverbs" with Emily Brewster
part of the "Ask the Editor" series at Merriam-Webster.com There are now only a few flat adverbs, and some are widely thought of as incorrect. Despite bare adverbs being grammatically correct and widely used by respected authors, they are often stigmatized. There have even been public campaigns against street signs with the traditional text "go slow" and the innovative text "drive friendly."

Bare adverbs that alternate with -ly forms

For most bare adverbs, an alternative form exists ending in ''-ly'' (''slowly''). Sometimes the ''-ly'' form has a different meaning (''hardly'', ''nearly'', ''cleanly'', ''rightly'', ''closely'', ''lowly'', ''shortly''), and sometimes the -ly form is not used for certain meanings (''sit tight'', ''sleep tight''). The adverb ''seldom'' is a curious example. It dates back to Anglo-Saxon times, but starting in the 1960s the same word began appearing in English books as ''seldomly''. It has been hypothesized that the decline in usage of ''seldom'' in English, combined with the 18th century insistence on adverbs ending in ''-ly'', resulted in its occasionally used ''-ly'' form. Similarly, usage of the word "thus" has fallen since 1800 – while usage of an ''-ly'' form, ''thusly'', has spiked recently.

Numerical adjectives (''first,'' ''second'', ''last'') rarely are used in an ''-ly'' form despite having a valid alternative. While words like ''firstly'' and ''lastly'' exist, their flat form is much more commonly used. Here, in contrast to other flat adverbs such as ''good'' ("they cook ''good''"), the flat form is universally accepted in English as proper speech.

Bare adverbs that do not alternate

Some bare adverbs don't alternate; e.g. ''fast'', ''straight'', ''tough'', ''far'', ''low.'' In addition, the ending ''-ly'' is also found on some words that are both adverbs and adjectives (e.g. ''friendly'') and some words that are only adjectives (e.g. ''lonely'').

Nearly all irregular comparative adjectives in English can take on adverbial form and never use the ''-ly''. Some examples are ''good, bad, little, much,'' and ''far'' – and their comparative forms (e.g. ''better'' and ''best'').

''My best number was the one I'd practiced least.''

''Which one hurt more?''

''Steel and coal companies were the ones worst affected by tariffs''.

Analyses of bare adverbs

Flat adverbs work as intensifiers that modify specific words. Consider sentences containing ''real'' and ''really'' (* signifies ungrammaticality):

''I really like the pie.''

''I real like the pie.*''

Here, ''real'' becomes ''really'' to become an adverb to the verb ''like'', while ''real'' cannot do the same and remain flat. According to data from the Corpus of Contemporary American English, ''real'' was followed by a verb only 657 times. For comparison, ''real'' was followed by an adjective 12,813 times, with ''good'' being the most common adjective collocated (1,584 times). In this case, ''real'' can only modify adjectives.

''This pie tastes really good.''

''This pie tastes real good. (informal)''

''This pie really tastes good. (meaning is changed)''

''This pie real tastes good.*''

Alternatively, the flat adverb ''sure'' can only modify verbs. Citing data from the Corpus of Contemporary American English, ''sure'' was followed by a verb 7,396 times, but it was rarely followed by an adjective at only 470 times. Compare:

''We sure had a great time.''

''We surely had a great time.''

''We had a sure great time.*''

''We had a surely great time. (meaning is changed)''

This can possibly be explained by the differing uses of the suffix ''-ly,'' and another adverbial suffix, ''-e''. According to the Oxford English Dictionary, there are two different uses of the suffix ''-ly'': when the suffix transforms a word into an adjective (e.g. ''brotherly''), and when it forms an adverb. The suffix's origins are in Old English, coming from -''lice'', which is related to the German -''lich''. Due to its use in history, many verbs and adverbs have been formed from roots that are harder to recognize today (compare: ''verily'' as ''very''+''ly,'' ''only'' as ''one''+''ly, especially'' as ''especial''+''ly''). Before ''-ly'', ''-e'' was the most common adverbial suffix in Old English. The suffixes were not competing and could even be used interchangeably (''rhyte – rhytlice'' are both '''rightly'''). Examinations of texts from the time period show that the -''e'' form was more common in poetry, while the ''-lice'' form was more common in prose.

As English developed as a language, it began weakening its vowels, and as such the -''e'' suffix gradually disappeared, making the adverbs bare. Some words retained adverbial use without the -''e'', such as ''long, fast'', or ''hard''. The adverbs had dwindled in number but did not die out entirely.

At this point in Old English, the adverbial system was still not as developed as it would become in later stages. Sentential adverbs were beginning to be developed and adverbs became used in more specific ways, and the vowel weakening -''e'' in tandem with more easily expressed -''ly'' forms caused -''ly'' to become the dominant adverbial form. Although there were no categorical changes between flat adverbs and the new adverbs, their use was generally limited. More and more adverbs took on this form for greater homogeneity among the class. John Earle wrote that a flat adverb was "simply a substantive or an adjective placed in the adverbial position." However, he found that flat adverbs are not suitable for many of the advanced uses that a modern adverb might be. An example of a more advanced adverb would be the sentential ''naturally'', as in ''naturally, we got along''.

Acceptability over time

The term 'flat adverb' was coined in 1871 by John Earle, and even in that time they were viewed as "rustic and poetic" because they were "archaic". Flat adverbs were relatively common in English through the 18th century, although more so in the United States. Earle writes that the flat adverb was "all but universal with the illiterate". One recorded example of their use is in letters by author Jane Austen. She used ''near'', ''exceeding'', and ''terrible'' as flat adverbs in one letter – and usage such as this was common in spoken discourse.

Although grammarians stigmatized them, flat adverbs are found to be accepted by English speakers and their usage has grown over the past century. A survey carried out in the 1960s studied people's attitudes towards usage problems in English. The examples "you'd better go slow" (rather than ''slowly'') and "he did it quicker than he'd ever done it before" (rather than ''more quickly'') contained flat adverbs – and the latter was found to be acceptable by just 42% of respondents. However, in a follow-up in the 2010s by the Leiden University Centre for Linguistics, using the same examples from the 1960s survey and others containing flat adverbs, they found that acceptance of flat adverbs has become much more widespread in recent years. ''Quicker'' was found to have an acceptance rate of 75%, while "you'd better go slow" was universally accepted.
