Why It Matters

Grammar affects meaning — comma placement, pronoun choice, and voice selection all change how sentences are understood. For reading comprehension, grammar knowledge helps students parse complex sentences with multiple clauses. Current best practice favours teaching grammar in the context of real writing rather than isolated drills. Learning rules through your own sentences is more relevant and memorable than abstract exercises.
