8.49 Reason clauses

When you want to indicate the reason for something, you use a reason clause.

Here is a list of the main conjunctions used in reason clauses:

8.50

If you are simply indicating the reason for something, you use 'because', 'since', or 'as'.

8.51

You use 'in case' or 'just in case' when you are mentioning a possible future situation which is someone's reason for doing something. In the reason clause, you use the simple present tense.

When you are talking about someone's reason for doing something in the past, you use the simple past tense in the reason clause.

8.52

'In that', 'inasmuch as', 'insofar as', and 'to the extent that' are used to say why a statement you have just made is true. These are formal expressions.

8.53

People sometimes use reason clauses beginning with 'for' or 'seeing that'. 'For' means the same as 'because'. Its use in reason clauses is now considered to be old-fashioned.

'Seeing that' means the same as 'since'. It is used only in informal speech.

'Now' and 'now that' are used to say that a new situation is the reason for something. Clauses beginning with 'now' or 'now that' are dealt with as time clauses. They are explained in paragraph 8.18.
