Learner notes
Memory Tip
联想：slacken = slack（松弛）+ en（使），像把绷紧的绳子松开，力度或紧张感渐渐减弱。
Context & Register
语域：mixed 常见场景：书面描述速度或强度变化、放松绳索或张力等操作说明、正式或叙事性散文 slacken 在具体操作（如放松绳索）和抽象描述（如速度、强度减弱）中都可能出现，但整体比较常见于书面或较正式场合；口语中表示“放松、松开”更常用 loosen，表示“放慢”更常用 slow down。
Grammar Note
Can be used transitively (e.g., slacken a rope) or intransitively (e.g., the rope slackened).
Pronunciation & Spelling
