The word Eventually AGAIN. My main headache. Still brooding

Huh?

You’ll get used to it eventually. (in the end). I promise.

It is not like in German where eventuell means perhaps.

Is it only English where “eventually” means “in the end” or “in time”? It seems to mean “perhaps” in other European languages.

In Portuguese it indicates that something is possible:
Usa-se para indicar uma possibilidade (ex.: o problema é eventualmente maior do que parece). = TALVEZ

“eventualmente”, in Dicionário Priberam da Língua Portuguesa - 2008-2013, eventualmente - Dicionário Online Priberam de Português
