Hi,

If you are comparing these two, you are probably thinking about conjunctions.

'So' is a conjunction. He loved her, so he married her.

'Therefore' is not classed as a conjunction, strictly speaking, although it is often used as one.

He loved her. Therefore, he married her.

He loved her, and therefore he married her.

(Descartes did not use the English word 'therefore' when he said the much-quoted 'I think, therefore I am'. He said 'Je pense, donc je suis', and 'donc' is considered a conjunction in French.)

Best wishes, Clive
