‘than’ used with comparatives
Than is mainly used after comparative adjectives and adverbs.
I am happier than I have ever been.
They had to work harder than expected.
If you use a personal pronoun on its own after than, it must be an object pronoun such as me or him.
My brother is younger than me.
Lamin was shorter than her.
However, if the pronoun is the subject of a clause, you use a subject pronoun.
They knew my past much better than she did.
He's taller than I am.
You can also use ever or ever before after than. For example, if you say that something is ‘bigger than ever’ or ‘bigger than ever before’, you are emphasizing that it has never been as big as it is now, although it has always been big.
Bill worked harder than ever.
He was now managing a bigger team than ever before.

Don't use ‘than’ when you are making comparisons using not as or not so. Don't say, for example, ‘He is not as tall than his sister’. You say ‘He is not as tall as his sister’.

You use rather than when you want to compare something that is the case with something that is not.
