There are several books excellent at teaching grammar. My own favourite is The Elements of Style by Strunk and White (various editions exist, all do the job).
While precise grammar is appropriate for some audiences, I would discourage valuing it too highly. If the central characteristic of writing well is to put an idea in somebody else’s head, then shouldn’t we optimize for efficiency?
