as soon as you see a chance

Soon ripe, soon rotten

Soon I will buy a new computer.

Sooner or later in political life one has to compromise.

No sooner said than done

sooner or later

No sooner had I put the phone down than it rang again

Sooner or later, fashion comes full circle

as a sop to someone’s pride

A sop in the pan

soppy

sore loser

sore spot

A sorrow shared is a sorrow halved!

a sorry sight

I'm sorry, I didn't catch your name.

I’m sorry for her

I’m sorry - [that was] my bad!

I'm sorry, but I have to go home now.

Sorry, I can't make it.

to be in a sorry state

Sorry,your name has gone out of my head.

I'm sorry I said that.

I am sorry,your name escaped me.

I'm sorry I hurt your feelings.
