10.6 - Verbs
The TKT glossary states that a conjunction (or connector) is used to connect words, phrases, clauses or sentences, e.g. I like tea but I don’t like coffee because it’s too strong for me.
Conjunctions are linking words like and, or, but, then and because. The two main types of conjunctions are coordinating (words such as and and but) and subordinating.

Temporal subordinating conjunctions are words such as when, while, before, after, until, once, as soon as. To know more about conjunctions, you can click here.
