eliminate: [16] To eliminate somebody is literally to ‘kick them out of doors’. The word comes from the past participle of Latin ēlīnāre, a compound verb formed from the prefix ex- ‘out’ and līmen ‘threshhold’ (source also of English subliminal and probably sublime). At first it was used in English with its original Latin sense (‘the secounde sorte thearfore, that eliminate Poets out of their citie gates’, Giles Fletcher, Christ’s Victorie 1610), and it was not until the early 18th century that the more general modern notion of ‘exclusion’ began to develop.
