Wiktionary:Merriam-Webster

Merriam-Webster (MW) is a classic popular American dictionary. The purpose of this page is to document some of its practices since some may find them inspiring or interesting.

Inclusion criteria
The requirements per MW&apos;s official guide are that to be included, "a word must be used in a substantial number of citations that come from a wide range of publications over a considerable period of time." Another guide mentions "frequent use, widespread use, and meaningful use". In the words of Kory Stamper, MW requires entries to have "accumulated and sustained use in print".

Descriptivism
MW takes a moderately descriptivist stance. In the words of Kory Stamper, "What good is a dictionary that enters irregardless but neglects to tell you that it’s not accepted as standard English? And how good is a usage and style guide that merely parrots rules with no careful consideration for the historical record of edited prose, or whether this rule does indeed produce clearer, cleaner writing?" Indeed, MW labels irregardless as "nonstandard".

Slang
MW includes slang and takes a descriptivist stance toward it, regardless of complaints. This includes Internet slang.

Proper nouns
Unlike OED, MW includes a fair amount of proper nouns, especially geographic names and biographical names. Examples:
 * First names and surnames:
 * No first names as first names and no surnames as surnames. Peter is an entry, but not for first name.

Hyphenated prefixed words
