Do you mean that a normal period lasts 45 minutes? If that is the case then the second half of a double period would be the second period. However, 'period' is really for school, not university. I'd say tutorial or class depending on what it actually is.
I am looking for some word to describe a 1.5 hour class which consists o two 45 min lessons, but lasts without a break (in a university). We call it "a pair" in my language, it's just a very long lesson. I suggested "a double period" because it is actually "a pair of periods" in time. But I 'd like to know some better word for it. We often say (in my language):
In our first "pair" we had English (Literature).
We have a long break after the second "pair" (= a long lesson of 45+45 min)
This devision of the "
pair" in two lessons is just nominal. Lectures and seminars are also "pairs" in my language. The "content" of the "pair" doesn't matter at all. So, can I use
tutorial instead of the
"pair" in the above sentences? ("After the second tutorial (= lecture/seminar/some other type of lesson... etc) we'll meet in the hall) For example, if two students from different groups have three "pairs" today (one has a seminar and two lectures, the other has English (
a practical lesson - a
tutorial?, a seminar and a lecture) and they want to meet, they don't need to say
Let's meet after the seminar and a lecture. Instead they may say
Let's meet in the yard after the second pair.
So "a pair" is a very general word used for ALL types of classes.
