Etymology
Etymology Information

'anilid' originates from English, specifically the word 'anilide', where the suffix '-ide' meant 'derivative of' and the root 'anil-' came from 'aniline'.

Historical Evolution

'aniline' (from Portuguese 'anil' and ultimately from Sanskrit 'nīlī') combined with the French/English suffix '-ide' to form 'anilide' in the 19th century; a shorter variant spelling 'anilid' also appeared and persists as a technical variant.

Meaning Changes

Initially, it meant 'an amide derived from aniline'; later usage also included the sense of 'the conjugate base (anilide ion)'.
