Noun (名詞)

Stroke Order

Meanings

  • deep bond and mutual trust beyond casual friendship
  • often used with 私の to denote one’s own close friend
  • found in personal writing and conversations to convey loyalty and intimacy

Etymology

しんゆう is the on’yomi reading formed from 親 and 友; the phonetic evolution reflects Sino-Japanese phonology, with a long vowel indicated by う in 友, yielding shin’yū in standard romanization.

Composition

  • 親: intimate, close; conveys affection and proximity
  • 友: friend; companion or ally
  • Combining these two concepts forms a term for a person who is a deeply trusted, close companion

Usage

Used to denote a very close, trusted friend; in casual speech, 私の親友 or 親友がいる; in formal writing, 親友 as a strong label in descriptions; it appears with particles such as 私の親友と過ごす and 親友に感謝する, emphasizing the depth of the relationship.
💡 Tips
Mnemonic: picture two people embracing with a heart between them, anchored by the idea that 親 signals closeness and 友 signals friendship; when you see 親友, imagine a lifelong bond with your closest ally.
