“close-set growth of shrubs, bushes, trees, etc.; tangled coppice or grove,” late Old English þiccet, from þicce in the sense of “dense, growing close together” (see thick (adj.)) + denominative suffix -et. Absent in Middle English, reappearing early 16c., perhaps a dialectal survival or a re-formation.
Totally pointless tangent: looking up “copse” on the Galnet translation dictionary (free, offline, fdroid) the Deutsch word is dickicht
…totally appropriate loanword to steal IMO. Adventure… linguistically!
Sounds similar to the English word thicket.
