1.Clauses Recap

1.1The Basics

A clause is a group of words that contains a subject and a verb. It can function as a whole sentence (a main clause) or as part of a sentence ( a subordinate clause).

Main Clause Subordinate Clause
(needs more information to be a full sentence)
also called Independent Clause
expresses a complete thought and can stand alone as a sentence
also called Dependent Clause
does not express a complete thought and cannot stand alone; needs to be connected to an independent clause.
Examples: Examples:
She will help me.
I would go for a walk.
We’ll go out.
You’ll pass the test.
If I ask her about it
If it weren't that cold
If the meeting ends
If you study hard
There are different types of Subordinate clauses (see Topic Clauses).
We normally express a condition using an if - clause with a main clause.
Conditional sentences / Conditionals are often categorised as: Zero, First, Second, Third, Mixed and False.

1.2When and If

The words Wnen and If are similar in many languages but different in English:

Example Meaning
If you come to my place tonight, we'll have dinner together. = you may come
When you come to my place tonight, we'll have dinner together. = you are coming.
