Prepositions of time

Prepositions - it's one of the grammar topics that might be complicated for English learners. Moreover, it's not the topic that can be logically learned, it's only learning by heart.

Prepositions of time - here's a list of the time words that need 'on', 'in', 'at' and some that don't need any preposition. Be careful - many students of English use 'on' with months (it should be 'in'), or put a preposition before 'next' when we don't need one.

Let's look through the list of the prepositions of time:
