-më

suffix. abstract noun

- (2) abstract suffix, as in melmë "love" (cf. the verb mel-), #cilmë "choice" (possibly implying a verb *cil- "to choose"). According to PE17:68, primitive - (and -) were endings used to derive nouns denoting "a single action", which may fit the meaning of cilmë (but melmë "love" would normally be something lasting rather than "a single action").
