Usage Reminders
- 1) Learn the three main parts of speech. 2) Remember key collocations: slack rope, slack off, with a slack in the schedule. 3) Distinguish physical slack from behavioral slack. 4) Pay attention to context to choose not tight vs lazy meaning. 5) Practice with both passive (the rope is slack) and active (slack off at work) usage.
