Fossil word

A fossil word is a word that is broadly obsolete but remains in use due to its presence in an idiom or phrase.^[1][2] An example of a word is 'ado' in 'much ado'. An example of a phrase is 'in point' (relevant), which is found in the phrases 'case in point' (or 'case on point' in the legal context) and 'in point of fact', but is rarely used outside of a legal context.

English-language examples

• ado, as in "without further ado" or "with no further ado" or "much ado about nothing", although the homologous form "to-do" remains attested ("make a to-do", "a big to-do", etc.)
• amok, as in "run amok"
• asunder, as in "torn asunder"
• bandy, as in "bandy about" or "bandy-legged"
• bated, as in "wait with bated breath", although the derived term "abate" remains in non-idiom-specific use

• betide, as in "woe betide you/us/them"
• bide, as in "bide your time"
• champing, as in "champing at the bit", where "champ" is an obsolete precursor to "chomp", in current use

"Born fossils"

These words were formed from other languages, by elision, or by mincing of other fixed phrases.

• druthers, as in "if I had my druthers..." (formed by elision from "would rather"^[12] and never occurring outside this phrase to begin with)
• tarnation, as in "what in tarnation...?" (evolved in the context of fixed phrases formed by mincing of previously fixed phrases that include the term "damnation")
• nother, as in "a whole nother..." (fixed phrase formed by rebracketing another as a nother, then inserting whole for emphasis; almost never occurs outside this phrase)
