同義詞
  • sign

    The most common and general word; 'indication' is slightly more formal and often used for less obvious evidence.

  • clue

    Suggests a piece of evidence used to solve a mystery or puzzle; 'indication' is broader and not limited to mysteries.

  • hint

    Weaker and more indirect than 'indication'; a hint is subtle, while an indication can be clear and direct.

文法句型

indication + of + noun phrase

indication + that-clause

用法筆記

Often used in fixed phrases like 'there is every indication that' and 'give every indication of' to emphasise strong evidence. The preposition 'of' introduces the thing being indicated, while 'that' introduces a full clause.

同義詞
  • signal

    More deliberate and direct; a signal is consciously given, while an indication may be an unintentional sign of what to do.

  • cue

    Strongly implies a prompt for a specific action, especially in performance or sequential tasks.

文法句型

indication + that-clause

indication + to-infinitive

take + noun phrase + as an indication + to-infinitive

用法筆記

Unlike sense 1 (SIGN OR CLUE), this sense carries the meaning of a recommendation — the situation itself points toward a necessary action. Often replaceable with signal or cue. Common in professional and planning contexts.

常見錯誤

✅My manager instructed me to finish the report by noon.
💡If someone has authority to order you, use 'instruct' or 'tell'. 'Indication' only suggests what is advisable.

    Broader term for any sign of illness; 'indication' is narrower — it specifically justifies a treatment, not just describes a condition.

反義詞

文法句型

indication + for + noun phrase

用法筆記

Primarily a medical term used by doctors and healthcare professionals. Unlike sense 1, which focuses on any sign of truth or events, this sense is restricted to symptoms that justify a specific treatment or procedure.

常見錯誤

❌The patient's headache was an indication for a cold.
✅The patient's headache was a symptom of a cold.
💡Use 'symptom of' for describing what illness a person has; use 'indication for' for which treatment is needed.
