So as a conjunction

Posted by Manjusha. Filed in English Grammar

So can mean as well or also in the structure so + auxiliary verb + subject. This structure is used to add something to the sentence before. Note that the auxiliary verb used with so is the same as the auxiliary verb used in the first sentence.

This structure can also be used with be and have.

If the first sentence doesn’t have an auxiliary verb, we use do / does / did with so.

So as a subordinating conjunction

So can be used to refer to the reason for something.

In a more formal style, we can express the same idea using as- and since-clauses.

Note that as and since introduce the reason while so introduces the result.
