Although uses such as "Life isn't really like it is in the movies," "It looks like it's going to rain," and "shoes like a dancer wears" still draw criticism, there is no doubt that, after 600 years of use, conjunctive like is firmly established. In modern use it may be found in literature, journalism, and scholarly works as well as informal speech and writing. Nevertheless, when writing in a formal prose style, you may prefer to use constructions such as "Life isn't really as it is in the movies," "It looks as if it's going to rain," and "shoes such as a dancer wears" to avoid possible criticism. as 3 of 9 pronoun 1 : that , who , which — used after same or such in the same building as my brother … tears such as angels weep … — John Milton and chiefly dialect after a substantive not modified by same or such … that kind of fruit as maids call medlars … — William Shakespeare 2 : a fact that is a foreigner, as is evident from his accent as 4 of 9 preposition 1 a : like sense 2 They all rose as one man. b : like sense 1a … his face was as a mask which revealed nothing. — Max Beerbohm 2 : in the capacity, character, condition, or role of works as an editor as 5 of 9 noun ˈas plural asses ˈa-ˌsēz ˈa-səz 1 a : a bronze coin of the ancient Roman republic b : a unit of value equivalent to an as coin 2 : libra sense 2a As 6 of 9 abbreviation (1) altostratus As 7 of 9 symbol arsenic AS 8 of 9 abbreviation (2) 1 after sight 2 airspeed 3 American Samoa 4 Anglo-Saxon 5 antisubmarine 6 associate in science as- 9 of 9 prefix see ad- Synonyms of as Relevance Conjunction when while See All Synonyms & Antonyms in Thesaurus Examples of as in a Sentence Adverb He was angry, but she was just as angry.
