Grammar in Use
Grammar becomes teachable when form, meaning, and context meet in the same room. A rule that collapses after the first authentic example is not much of a rule. Here, timelines and sentence patterns lead into choices learners can make for themselves. Variation is acknowledged where it matters, especially across Englishes.
