Modifying an adjective:
-

-
It is stronger than fairly, but not as strong as very.
- It can modify a noun, often coming before the article:
-
It's rather a problem.
-
It can modify some verbs: I rather like it.
B) To express preference
Rather than:
Rather than is normally used to compare parallel structures:
-

-
Rather you than me!
-

Would rather:
Would rather + infinitive without 'to':
Would rather + pronoun + past tense:
