There are four very different seasons in Finland. Seasons' changes bring a natural cycle in life,
where for example leisure activities change along with seasonal changes.
Finns tend to speak about the weather and it is a common small talk topic.

If you add –lla or -llä at the end of the of the season word e.g. syksy fall syksyllä you get a new meaning which is in the fall.

kevät - keväällä spring - in the spring

syksy - syksyllä fall - in the fall

kesä - kesällä summer - in the summer

talvi - talvella winter - in the winter
Note that in talvi the final -i changes to -e when the ending is added. The stem is talve-
