Learn Spanish (Spain): Todavía no puedo acostumbrarme a este clima.

In Spanish, the verb acostumbrarse (to get used to) is a verb of prepositional regime. This means it always needs a specific preposition to connect to the noun or infinitive that follows it. For acostumbrarse, that preposition is always a. So, getting used to this climate requires the phrasing acostumbrarse a este clima.

Why is the pronoun me attached to the end of acostumbrar? Could it go anywhere else?

Yes! When you have a conjugated verb (puedo) followed by an infinitive (acostumbrar), you have two choices for pronoun placement. You can attach it to the end of the infinitive, as in no puedo acostumbrarme, or you can place it right before the conjugated verb, like no me puedo acostumbrar. Both are completely natural and mean exactly the same thing.

The word clima ends in the letter a, so why do we use the masculine word este instead of esta?

Clima is one of several Spanish words of Greek origin that end in -ma but are actually masculine. Other common examples you might remember are el problema, el tema, and el idioma. Because clima is masculine, it must take the masculine demonstrative adjective este.

Could I use aún instead of todavía at the start of this sentence?
