Learn Spanish (Latin America): Mi estación favorita es el verano.

In Spanish, when you talk about seasons in a general sense, as a preference, or as the subject of a sentence, you usually need to include the definite article (el or la). So "summer" becomes el verano.

Wait, doesn't estación mean "station", like a train station?

Yes, it does! Estación is a word with two very common meanings: a season of the year (like summer or winter) and a transit station (like la estación de tren). You can easily tell which one is meant by the context of the sentence.

How do I know that estación is a feminine word? It doesn't end in an "a".

A very helpful rule of thumb in Spanish is that almost all words ending in -ción are feminine. Because estación is feminine, the adjective describing it must also be feminine. That is why we use favorita instead of the masculine favorito.

Why is the word order estación favorita instead of favorita estación?

In Spanish, adjectives (describing words like favorita) usually come directly after the noun they describe (estación). So instead of saying "favorite season" like we do in English, the structure is literally "season favorite".
