Meanings

  • Indicating departure or the act of leaving to begin an activity, often implying intention or plan rather than mere motion.
  • Expressing the passage or progression of time or events (e.g., years or seasons moving on).
  • Used colloquially to mean “that will do” or “that works” when approving a choice or plan.
  • Appears in compounds and set expressions to mark directionality or movement of a process rather than literal travel.
  • In literary or poetic registers (written as 往く (yuku)), used as a euphemism for departing life or moving to another realm.

Origin

Attested since Old Japanese and classical literature (Man’yōshū and Heian texts), the verb survives in both kana spellings いく and archaic ゆく; its written representation with the kanji became standardized as writing practices evolved from classical to modern Japanese, reflecting long-standing everyday action and travel in social life.

Composition

The kanji combines the left-side step radical 彳 (associated with walking/steps) with remaining strokes that historically evoke a path or going; readings include the kun-yomi iku/yuku and on-yomi /gyō, and the character’s graphic elements emphasize motion and direction rather than unrelated concepts.

Usage

Common across all registers, from casual to polite: the plain form appears in everyday conversation, the -ます form in formal speech, and various conjugations serve functions like invitations, commands, and nominal clauses; typical contexts include describing travel or errands, making plans, giving directions, or marking transitions in narratives and instructions.
💡 Tips
Visualize the left radical 彳 as two stepping legs and remember that (iku) is the character you “step” with when you learn verbs about movement.

Variations

  • ゆく (yuku) — archaic/poetic alternate reading sometimes used in literature.
  • 来る (kuru) — antonym meaning “come” (opposite directional movement).
  • 出かける (dekakeru) — synonym emphasizing leaving home or going out.
  • 去る (saru) — synonym with nuance of departing or leaving, often formal or literary.
