Commonly Confused Prepositions: in, on, at, to, for, and since

In Spanish, en covers in, on, and at. In Portuguese, em does the same. And in French, depuis handles both since and for. When you translate directly into English, you end up saying things like I'll meet you in 6 pm or I've studied English since three years — mistakes that are perfectly logical in your language but immediately mark you as a non-native speaker in English.

This challenge targets the exact preposition mix-ups that trip up speakers of Romance languages. You will practice choosing at for clock times, on for days, and in for months and years. You will also master the difference between since (a starting point: since 2019) and for (a duration: for three years), and learn when to use for (recipient) instead of to (direction).

You'll work through 12 questions in a mix of single-choice, multi-choice, drop-down, and drag-and-drop formats featuring time-traveling spies, vampire dating profiles, and soap opera plot twists.
