Etymology

Perhaps from bōs ‎(“cow”) +‎ -ētum ‎(“place”), by analogy to fruticētum, salicētum, and senticētum for the epenthetic -c- and būcina ‎(“horn”) and būculus ‎(“young bull”) for the būc- stem form.
Others have proposed the combination of bōs with Proto-Indo-European root *kait-, *ḱait- ‎(“forest, wasteland, pasture”) (whence Proto-Germanic *haiþī ‎(“heath, wasteland”)). This however does not seem to account for the change from Proto-Indo-European -ai- to Latin -ē- (or -ī- in būcītum).
