Etymology

From Middle English extremite, from Old French extremité, from Latin extrēmitātem (“extremity; border, perimeter; ending”), from extrēmīs (“furthest, extreme”) + -itās (ultimately from Proto-Indo-European *-teh₂ts (suffix forming nouns indicating a state of being); see extreme. Extrēmīs is derived from exter (“external, outward”) (ultimately from Proto-Indo-European *h₁eǵʰs (“out”)) + -issimus (superlative suffix) (ultimately from Proto-Indo-European *-is- (comparative suffix) + *-(t)m̥mo- (absolutive case suffix)).
