Learn Italian: Il tuo avversario è astuto e prevede la mossa meglio di prima. - Your opponent is cunning and foresees the move better than before.

Meglio is an adverb, which means it describes a verb. In this sentence, it describes how the opponent foresees (prevede) the move. Migliore is an adjective used to describe nouns (like a "better opponent"). Since we are talking about doing something better, we use meglio.

Why does di mean "than" in the phrase meglio di prima?

When comparing things in Italian, "than" is usually translated as di or che. Before an adverb of time like prima (before), you use di. So, "better than before" translates directly to meglio di prima.

Is the verb prevede conjugated just like vede?

Yes! Prevedere (to foresee or predict) is formed by adding the prefix pre- to the verb vedere (to see). You can conjugate it in any tense simply by putting pre- in front of the standard vedere forms.

Why is there an il before tuo avversario? Doesn't that mean "the your opponent"?
