The final closed class you’ll consider here is the conjunctions. These are words which join things together. Conjunctions can join single words (bread and butter, tea or coffee, naughty but nice) or they can join short statements into longer sentences, such as We ate the biscuits and drank the milk or He wanted to go for a walk but it started to rain.
These conjunctions (and, or, but) are simple linking words. There are other conjunctions which are used to build up complex sentences, making logical and grammatical connections between the different parts. For example:
People got angry because we ran out of biscuits
It’s easy when you know the answer
I’ll text you if I have any problems
You’ll learn more about this type of conjunction in Week 7.
