This is the 184th most frequent Finnish word.
en
"En" is the Finnish word for "I don't" or "I do not."
Here, 'en' translates to 'I don't' and is the first-person singular form of the negative verb in Finnish.
En puhu englantia.
I don't speak English.
In this sentence, 'en' is part of the negative construction and it again means 'I don't' or 'I am not'.
En ole varma.
I am not sure.
'En' in this sentence negates the verb 'käy' (go), making it clear that the action is not performed.
