From Middle English spoon, spoune, spone, spon, from Old English spōn, from Proto-West Germanic *spānu, from Proto-Germanic *spēnuz, from Proto-Indo-European *(s)peh₂-.
Cognate with Scots spun, spon, West Frisian spoen, Dutch spaan, German Span, Faroese spónur, Ancient Greek σφήν. Eclipsed non-native Middle English cuculer and coclear both ultimately borrowed from the Latin.
