Nearly the only quote in the course that warrants an exclamation, apart from "Käärme!" .
Could viileä counted as well
difference between kylmä and kylmää ?
Sauna is countable, so the adjective is in nominative kylmä.
For an uncountable noun it would be in partitive, for example Vesi on kylmää (the water is cold).
Kaisa is one of the few Finnish names I have known before starting this course. A beautiful name.
