Gnomish
belu-
verb. to unroll, unfurl (intransitively), belly (of sails), swell
belwa-
verb. to unroll, unfurl (intransitively), belly (of sails), swell
A verb appearing as belu- or belwa- in the Gnomish Lexicon glossed “unroll, unfurl (intransitively), belly (of sails), swell” in the Gnomish Lexicon of the 1910s (GL/22), clearly based on the early root ᴱ√VELU (or ✱ᴱ√BELU) “unroll” (QL/100).
@@@ maybe salvage belwa-?
