Etymology Origin:
The word "residual" traces back to Latin residuum (something remaining), derived from residere (to remain sitting, stay behind). The components re- (back) and sidere (to sit) metaphorically convey the idea of "what sits back" or "what is left behind." Over time, it evolved into Middle French résiduel before entering English in the 16th century, retaining its core meaning of "remaining" or "leftover."
