We use rather as an adverb of degree:
• The film was rather good.
Modifying an adverb:
• It happened rather quickly.
2. It can modify a noun, often coming before the article:
3. It’s rather a problem.
4. It can modify some verbs: I rather like it.
B) To express preference
Rather than is normally used to compare parallel structures:
• Let’s take the train rather than the bus.
• Rather you than me!
• I decided to write rather than email.
When the main clause has a to – infinitive, rather than is usually followed by an infinitive without to or -ing form.
e.g. – I decided to write rather than phone/phoning.
II. Would rather:
Would rather + infinitive without ‘to’:
• I’d rather leave now.
Would rather + pronoun + past tense:
• I’d rather he came early.
