Hyphens are the short lines that we put between the words in expressions like ex-boyfriend and non-alignment.

Two-part adjectives
The hyphen is used in two-part adjectives when the second part ends in -ed or -ing.

We do not normally use prepositions in some common expressions.

After certain verbs
The verbs enter, discuss, marry, lack, approach and resemble are usually followed by direct objects without prepositions.

That is simply connector. It shows that a clause forms part of a larger
sentence.

The noun time is countable in expressions like a long time, a short time and quite a time.

They took a long time to finish the job.
We have been hearing about this for quite a time.

A biography is the account of a person’s life written by another person. An example is ‘Life of Johnson’ written by Boswell. An autobiography is the story of a person’s life written by that person. An example is ‘My Experiments With Truth’ written by M.K. Gandhi.

The adverb too is used to show undesirable extremes. It has a negative meaning.

She is too fat.
He is too tired.

An infinitive structure is often used after too + adjective/adverb/determiner.

Negation

The label negation refers to the use of a negative element like not or a negative auxiliary like can’t.

Negative auxiliary
These are forms like don’t, can’t, doesn’t and won’t.
