season
The Italian word 'stagione' is used to refer to a season of the year, just like the English word 'season'. It can be used in contexts such as 'la stagione estiva' (the summer season) or 'la stagione invernale' (the winter season).
The summer season is my favorite.
This is a simple sentence stating a preference for the summer season. In Italian, 'La stagione estiva' means 'The summer season', 'è' means 'is', and 'la mia preferita' means 'my favorite'.
Which season do you prefer?
In this question, you're asking someone about their favorite season. 'Quale' means 'Which', 'stagione' is 'season', and 'preferisci' is the verb 'to prefer' in the second person singular form.

This sentence indicates when the rainy season begins. 'La stagione delle piogge' is 'the rainy season', 'inizia' means 'starts', and 'in aprile' is 'in April'.
