I did explain what it means though...

If you're uncertain or still don't understand, it's best to email your lecturer for clarification.

So you said : would mean

so in this case , R(R) is a subset of R ?
But is there a word for the semi-colon and what it actually means?

Left composition. It's the composition of relations.
