Please help, is this correct?Prefiero estudio por la tarde.

Question

Prefiero estudio por la tarde.

Answer 1

Prefiero estudiar por la tarde. I prefer to study/studying in the afternoon.

Answer 2

Hola, chicabonita

In your original question, the problem was that you accidentally switched verbs in question one.

The question asked when you preferred to study,and you wrote when you preferred to go.

This is what Geof was talking about in his answer, and as Keven has written, you were correct in the first place to follow prefiero with an infinitive.
