Compound noun: Back alley.
Taka is a noun which means ”backside.” All by itself, the noun taka is rarely used in modern Finnish, but some declined cases of taka– are used as postpositions and adverbs (taakse, takana, takaa, etc). (It’s interesting to note that many of the Finnish postpositions are cases of out-of-use Finnish words.)
Taka- is used in our example as a prefix meaning ”back,” ”rear” or ”hind.” Other compound nouns using taka are takaovi (”back door”), takapiha (”back garden” or ”backyard”), takatalvi (”recurring wintry weather in spring”), and takapuoli (”backside, buttocks, bum.”) (Many more are listed here.)
Another common word which comes from taka is the adverb taaksepäin, meaning ”in the direction towards the back” or ”backwards.”
Kuja is a noun which means ”alley,” ”alleyway” or ”lane.” Street names which contain kuja are more often seen in the country.
