juolukka.

juolu- + -kka (probably the origin of the form -ukka seen also in puolukka, vatukka), from Proto-Finnic *joo-, which is further related to Proto-Samic *joŋë (“lingonberry”), suggesting earlier *juŋe. Details The forms of this word vary widely, but the forms in Finnish, Ingrian and Votic generally follow the pattern *jooCukka (extended *jooCuk'as in Votic). In Finnish, besides -l-, -m- (juomukka), -p- (juopukka) and -v- (juovukka) are found, in Ingrian (joomukka) and Votic (joomukõz) only -m- (also in Ludic with a different suffix, dʹuomoi). All aforementioned Finnish forms also have variants ending in -ikka, which matches the forms seen in Veps (jońikaine), Estonian (joovikas) and Livonian (jūoimki, jūoipki). There are more Finnish variants too with different suffixes. The forms with -l- (only in Finnish) are likely by contamination with puolukka, while -v- (*-b-) is simply the weak grade of -p-, leaving only the question of whether -m- or -p- came first. According to Koponen (1991), both likely originate from association with words derived from *joodak (“to drink”), specifically *jooma (“drink”) and *joopudak (“to become drunk”). In that case, the -ukka likely originates from the -u- in the latter word and was later generalized by analogy. Semantically the berry is often associated with intoxication: compare German Rauschbeere, Swedish odon, Russian пьяника (pʹjanika).
