We use the prepositions in, on or at to say when something happens.


We usually use at with clock times and mealtimes.

I get up at 6.30 a.m. and go for a run.

We also use at with some specific phrases such as at the weekend and at night.

At the weekend, I can spend the days how I like.

We can also say on weekends or on the weekend. This is more common in American English.

Hello kikoo,

I would say 'at', but I think 'in' and 'with' are also used. Online courses are new linguistic territory!

Hello. Sorry these prepositions ("of" vs "from") aren't on the page. Which of these is correct? Or are they both? What's the difference in meaning?
- I almost cried of happiness when I saw my long-lost mum.
- I almost cried from happiness when I saw my long-lost mum.

Hi Howard Manzi,

The usual preposition would be "with": I almost cried with happiness. Using "from" is also possible, but less commonly used.

The preposition "of" is normally used when "cry" is a noun, not a verb (e.g. I gave a cry of happiness).

I hope that helps.
