English: so, part 0

Self-tutoring about English: the tutor discusses use of the word so.

The word so is a conjunction, but can also be an adverb. “I so often diet” might be an example.

Another use case for so:

(example 1:) Her advice is so valuable because it comes from years of experience.

One hears such sentences, yet reads them much less. Perhaps the reason is that so is often used as an adverb in talking, but usually as a conjunction in formal writing. Yet, indeed, the usage in example 1 is correct because so is being used as an adverb.
