remnant

Synonym discussion
Sense: noun/1
All four words refer to something that stays behind after the main part is gone, but they differ in context and connotation. Leftover is the most informal and everyday word, common for uneaten food or small unused items. Remainder is neutral and mathematical, often used for what is left after subtraction, division, or a batch process. Residue has a scientific or technical feel, suggesting a thin layer or small amount left on a surface after a process (e.g. soap residue on dishes). Trace is the most emphatic about smallness — it means an extremely tiny or barely detectable amount. You might say: 'After the party, we packed the leftovers into containers.' 'The chemical left a sticky residue on the glass.' 'The archaeologists found only traces of the original paint.'

Etymology
Remnant comes from the Latin verb remanēre, meaning 'to stay behind or remain', formed from re- ('back, again') + manēre ('to stay'). It passed into English through Old French remenant, which was the present participle of remaindre ('to remain'). The word has been used in English since the 1300s for things that stay behind when most of something is gone. The fabric-sense date to the late 1500s, when cloth merchants began selling leftover lengths of material at a discount.
