Recorded since 1570. From residue, itself borrowed during the Middle English period from Old French residu (Modern French résidu), from Latin residuum (“a remainder”), the neuter inflection of residuus (“remaining, left over”), perfect participle of resideō (“to remain behind”), from re- (“back, again”) + sedeō (“to sit, to reside”).
