‘to smile’
source: entry from Holle List; unable to verify c. 1900 note: lubayon is likely an archaic longer form of bayon ‘mouth’. The word lu can also mean ‘few in number’, but it is hard to imagine how that would help to form a term for ‘smile’. biha is a mystery, none of my guesses regarding possible abbreviations, contractions, and possible compounding seem logical for ‘smile’. It is of course possible that the form is a result of miscommunication and that it would make sense in context.
