to such a great extent

the words tumbled out so fast that I could barely hear them

don't look so worried

I'm not so foolish as to say that

to the same extent (used in comparisons)

he isn't so bad as you'd think

help without which he would not have done so well

referring back to something previously mentioned

in the way described or demonstrated; thus

hold your arms so

so it was that he was still a bachelor

and for this reason; therefore

it was still painful so I went to see a specialist

you know I'm telling the truth, so don't interrupt

with the aim that; in order that

they whisper to each other so that no one else can hear

and then; as the next step

and so to the final

introducing a question

so, what did you do today?

introducing a statement which is followed by a defensive comment

so I like keeping track of things—what's wrong with that?

introducing a concluding statement

so that's that

in the same way; correspondingly

just as bad money drives out good, so does bad art drive out the good
