Character Breakdown

Understanding 傷める (いためる)

The verb 傷める means "to damage" or "to harm" something, often referring to physical injury or impairment. It is a transitive verb, so it always takes a direct object — something that gets damaged or hurt.

Common Usage

傷める is frequently used when talking about damaging body parts (like eyes, stomach, or muscles), objects, or even abstract things like reputation. It often implies accidental or unintentional harm.

Collocations and Patterns

  • 目を傷める (めをいためる): to damage one's eyes — often used when discussing strain or injury from overuse.
  • 体を傷める (からだをいためる): to harm the body — common in health or exercise contexts.
  • 胃を傷める (いをいためる): to hurt the stomach — often related to medicine or food.

Register and Nuance

傷める is neutral and can be used in both casual and formal contexts. It is more specific than general verbs like 壊す (to break) because it often implies damage that affects function or health.

Common Learner Mistake

Confusing 傷める with 傷つける (きずつける), which also means "to hurt" but is more often used for emotional or psychological harm. 傷める is more physical or tangible damage.
