Object is usually a job, role, or task; the person receiving it appears either as a second object or after 'to'. Frequently passive — the receiver often becomes the subject ('she was assigned...').

The boss assigned me three reports.
💡no preposition before the task; use direct double object or 'assign X to me'.

  • allot

    formal; emphasises a fixed share of time

文法句型

assign + a time/date + for + something

assign + a time/date + to + something

Distinguish from sense 1: here the object is always a time slot or period, never a task or person. Often used in scheduling, study planning, or event organising contexts.

  • bind

    more technical; common in functional programming contexts

用法筆記

Technical use only — found in programming tutorials, code comments, and software documentation. The 'to' phrase always names where the value goes (variable, memory address, register).

Assign the value 5 to x.
💡value first, variable after 'to'.

6. to state, after thinking carefully, what you believe caused something to happen

    used when the cause is positive (success, achievement)

文法句型

assign + a reason/cause + to + something/somebody

💡use 'to' for the cause, never 'on'.

反義詞
  • retain

    to legally keep ownership rather than transferring it

文法句型

assign + property/rights + to + somebody

用法筆記

Strictly legal language — wills, contracts, intellectual-property documents. Distinguish from senses 1 and 2: this transfers OWNERSHIP, not a task or a posting. The receiver is called the 'assignee'.

常見錯誤

He assigned his house for his daughter.
He assigned his house to his daughter.
💡the recipient takes 'to', not 'for'.
