Usage

The intensive so meaning “very or extremely” ( Everything's so expensive these days ) occurs chiefly in informal speech. In writing and formal speech, intensive so is most often followed by a completing that clause: Everything is so expensive that some families must struggle just to survive. The conjunction so (often followed by that ) introduces clauses both of purpose ( We ordered our tickets early so that we could get good seats ) and of result ( The river had frozen during the night so people walked across it all the next day ). In formal speech and writing, so that is somewhat more common than so in clauses of purpose. Otherwise, either so or so that is standard. Like and, but1 , and or, so can occur as a transitional word at the beginning of a sentence: So all our hard work finally brought results. See also as ¹, and, but ¹.

In formal English, so is not used as a conjunction, to indicate either purpose ( he left by a back door so he could avoid photographers ) or result ( the project was abandoned so his services were no longer needed ). In the former case to or in order to should be used instead, and in the latter case and so or and therefore would be more acceptable. The expression so therefore should not be used

Synonym Usage

See therefore.

Etymology

Origin of so

First recorded before 900; Middle English; Old English swā; cognate with Dutch zoo, German so, Gothic swa
