the.com/remnant
the leftover that outlived everything it belonged to and refuses to admit it lost.
means A small piece or quantity of something that remains after the rest has been used, removed, or destroyed.
from From Old French 'remenant,' the present participle of 'remenoir' meaning 'to remain,' which traces back to Latin 'remanere' — 're-' (back) plus 'manere' (to stay, to dwell). Buried in there is the same root as 'mansion' and 'permanent,' all of them words for things that simply refuse to leave.
