be used in English as nouns meaning "morning" and "afternoon"; however, such use is consistent with ordinary nominalization features of English. AHD4 lists adjectival usage with "an A.M. appointment" and "a P.M. appointment". RH gives "Shall we meet Saturday a.m.?" without comment. Also, the National Institute of Standards and Technology contends it is incorrect to use 12 a.m. or 12 p.m. to mean either noon or midnight. amidst – Some speakers feel it is an obsolete form of amid. Amidst is more common in British English than American English, though it is used to some degree in both. amongst – Some speakers feel it is an obsolete form of among.

The OED says "In all senses, between has been, from its earliest appearance, extended to more than two". Chambers says "It is acceptable to use between with reference to more than two people or things", although does state that among may be more appropriate in some circumstances.
