When I left the station, I got sad.

When I was at university we went to the flicks every Thursday night

When he comes of age he will be responsible for what he does

when the chips are down

when wet or icy

when push comes to shove

When for?

When I like people immensely, I never tell their names to any one. It is like surrendering a part of them.

When I show you my house, you'll be green with envy.

When I have migraines, I often feel sick.

When the cat’s away, the mice will play

When the telephone bell rang, my heart went into my boots. I knew bad news was coming

When do you envisage finishing your studies?

When are you leaving?

When are you going swimming?

When do the fireworks start?

when nothing seems to go right anymore

When would it be convenient for us to meet

When will you be available to start the new job?

When one is sober, the bad can appeal. When one has taken a drink, one knows what’s real

When you sleep, your body has a chance to renew itself

When it’s gone, it’s gone

When I was your age...

When will that point arrive / be [reached]?

When does our flight arrive in New York?
