extremity

Arms (top) and feet are types of extremities (sense 3)

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