From eastern Middle Dutch boke, boeke, from Old Dutch *buoka, from Proto-Germanic *bōkijǭ. Western varieties of Dutch, including generally Standard Dutch, do not have umlaut of long vowels. The eastern variety with umlaut was probably adopted to avoid homonymy with boek.
Variant of buik.
- part of a church building, compare middenbeuk
beuk (plural beuks)
