1.形容詞A2
釋義

planned or scheduled by a set timetable to happen or be ready.

例句

The 9:15 train from Taipei is due to arrive at 10:45.

be + due + to-infinitive for schedules

Haruto's final project is due on Friday, so he is working late this week.

be + due + on + date for deadlines

同義詞
  • expected

    more general; 'due' adds the idea of a set schedule

  • scheduled

    stronger on planning; 'due' often implies a deadline

  • anticipated

    more formal, focuses on expectation rather than obligation

反義詞

文法句型

be + due + to-infinitive

be + due + on/at/in + time

用法筆記

Predicative only — do not use before a noun. You can say 'the report is due next week' but NOT 'the due report'.

常見錯誤

The due date is tomorrow.
The date is due tomorrow.
💡When 'due' is used predicatively, it follows the subject; 'due date' is a noun phrase where 'due' acts as an attributive adjective, which is acceptable for the fixed phrase 'due date'.

2. happening at the correct time after a natural period has passed, and not before.

2.形容詞B2
釋義

happening at the correct time after a natural period has passed, and not before.

例句

Your visa application will be processed in due course once the documents are verified.

fixed phrase: in due course (at the proper time)

The committee will announce the scholarship winners in due time after comparing all entries.

同義詞
  • eventually

    less formal; 'in due course' implies the timing is appropriate, not just eventual

  • in time

    shorter and more casual; 'in due course' adds formality

文法句型

in + due + course

in + due + time

用法筆記

Only appears in the fixed phrases 'in due course' and 'in due time'. Never use 'due' alone in this sense. The phrase carries a formal, patient tone and is common in official correspondence.

常見錯誤

I will finish it due course.
I will finish it in due course.
💡The preposition 'in' is required and cannot be omitted.

3. resulting from a particular cause, reason, or circumstance.

3.形容詞B1
釋義

resulting from a particular cause, reason, or circumstance.

例句

The flight was cancelled due to heavy fog at the airport.

due to + noun phrase expressing cause

Marta missed the meeting due to a family emergency.

同義詞
  • because of

    more common in everyday speech; 'due to' is slightly more formal but often interchangeable

  • owing to

    more formal; often used in written English

  • attributable to

    more technical; used in formal or academic writing

反義詞
  • despite

    marks contrast rather than cause

文法句型

due + to + noun phrase

常見錯誤

Due to I was sick, I stayed home.
Due to my illness, I stayed home.
💡'Due to' must be followed by a noun phrase, not a clause. For a clause, use 'because' instead.

同義詞
  • payable

    stresses the debt aspect; slightly less common in everyday use

文法句型

be + due + to + person

payment/amount + be + due

用法筆記

deserving or ready to receive something because of the time that has passed or one's achievements.

例句

After five years in the same role, Rachid is due for a promotion.

be + due + for + promotion/reward

The car is due for an oil change every six months.

同義詞
  • ready for

    more general; lacks the sense of deserving, just timing

  • deserving of

    focuses on merit; 'due for' adds the element of expected timing

文法句型

be + due + for + noun phrase

用法筆記

Only used predicatively with 'be due for'. The subject is a person or thing that is ready or deserving, and the object is the thing deserved or needed. Common with scheduled services (check-ups, inspections, maintenance).

常見錯誤

I am due a promotion.
I am due for a promotion.
💡The preposition 'for' is required in this sense, unlike in sense 4 ('I am due a refund' without 'for' means someone owes it to me).

proper and correct for a particular situation, often in formal contexts involving procedure or respect.

例句

due + care / attention / consideration

fixed phrase: with all due respect

同義詞
  • proper

    overlapping meaning, but 'proper' is broader and less formal

  • appropriate

    more widely used across registers; 'due' adds a sense of moral or procedural correctness

  • fitting

    emphasises suitability to circumstances

反義詞

文法句型

due + noun

with all + due + respect

用法筆記

Unlike other adjective senses, this one goes BEFORE the noun (attributive position). Common in formal, legal, and academic English. The phrase 'with all due respect' is used to politely introduce a disagreement.

常見錯誤

Please give the matter due.
Please give the matter due attention.
💡In this sense, 'due' must modify a noun; it cannot stand alone.

due — adverb

due — noun
