A Useful List of Idioms, A-F
This is a list of idioms (from A-F) in English and their meanings. It includes both phrasal verbs (verbs with a particle-- the special use of a preposition-- that can change their meaning) and other idioms, alphabetized by their first main word (not a, an, the, or to.) (See Phrasal Verb Use for an explanation of those very common verbs.)
For idioms starting with the rest of the alphabet, see List of Idiom Definitions, G-L, Idiom Meanings List M-S, and Idioms List T-Z.
