5.70 relative time

If you want to refer to a period of time in relation to another period of time, or in relation to an event, you use an adjunct. For example, you can use an adverb such as 'soon' or 'later' to refer to time which follows a particular event or period of time, and you can use an adverb such as 'beforehand' or 'earlier' to refer to time which preceded a particular period of time or an event.

This type of time reference is common with past and future tenses. It is sometimes used with present tenses when they are used to refer to past, future, or habitual actions.

Here is a list of adjuncts which are used to refer to time in a relative way:

Note that in this list 'presently' means 'soon'.

You can use 'early' to indicate that something happens before the expected or planned time, and 'late' to indicate that it happens after that time. 'On time', and 'punctually' are used to say indicate that something happens at the planned time.

These adverbs come after the verb and at the end of the clause.

With 'early' and 'late' you can also use the comparative forms 'earlier' and 'later'.

Note that 'early', 'late', and 'on time' are also used as complements.

For more information on complements, see paragraph 3.128.
