There are more to –nym words than just Synonyms and Antonyms :) I studied these terms in Grammar 101, but you know how and ageing mind is, it forgets. So here’s a nifty guide (some of them at least, because there are dozens out there!) to remind you that there words to classify, well, words:

Acronym: An abbreviation, pronounced as a word, consisting of the initial letters of a multiword name or expression; i.e. scuba for self contained underwater breathing apparatus.

Anepronym: A trademarked brand name now used generically, such as aspirin, xerox or kleenex.

Antonym: A word with opposite meaning with another; i.e. near is an antonym of far.

Eponym: A proper or common name deriving from another name, as San Francisco (in honor of St. Francis) or many scientific terms, such as watt (named after James Watt) and volt (from Allesandro Volta).

Heteronym: A word spelled (and usually pronounced) the same way but with different meanings, such as pen (writing instrument) as opposed to pen (an enclosure for sheep or pigs).

Pseudonym: A name adopted by an author (Charles Lutwidge Dodgson = Lewis Carroll), performing artists (stage names instead of real name), or handles (chat names etc).

Synonym: A word with the same meaning as another, such as small, as compared to little.

Toponym: A place name, whether it retains capitalization, or is lowercased in generic usage, such as manila.
