Hän kulki metsän poikki.

English Translation

He walked through the forest.

Can ‘kulkea’ mean ‘to walk’? It sounds wrong to me.

The sentence on Tatoeba was translated from English by a Finnish native speaker. I’m not a native speaker, but it sounds OK to me, probably because I’m used to seeing kulkea used in that sense.
