    passive equivalent with the same core meaning

反義詞
  • unblock

    the direct opposite — to clear the pipe so flow resumes

文法句型

pipe/drain + blocks up

block something up (transitive use)

用法筆記

This sense is most common intransitively (the pipe blocks up), describing an accidental or natural clogging process rather than a deliberate action.

常見錯誤

❌The pipe blocked up by me.
✅I blocked up the pipe.
💡When used transitively, the agent acts on the object; the passive form needs 'get' or 'become': 'The pipe got blocked up.'
