What does 時 mean?

Translation and Meaning

time, hour, moment

Definition

時 (toki) means a temporal point or span used to place events—covering moments, hours, and the general timing of actions; it functions as the basic word for ‘when’ in many grammatical structures and appears in clock expressions and time-related compounds.

Type

noun; temporal conjunction (名詞, 接続詞)

Stroke Order

Meanings

  • 1. As a temporal conjunction: used to mark ‘when’ something happens in subordinate clauses (expressing the timing of an action).
  • 2. As an on-reading in clock expressions: combined with numerals to indicate hours (the pronunciation and role differ from the kun reading).
  • 3. As a bound morpheme in compounds to form terms about points or spans of time rather than duration.
  • 4. Literary or idiomatic sense: can indicate occasions, seasons, or fixed moments in classical and poetic language.

Etymology

時 shows two main Japanese readings: kun’yomi toki, inherited from Old Japanese phonology, and on’yomi ji, borrowed through Middle Chinese; the modern pronunciations reflect these separate phonetic layers rather than a single vowel shift.

Origin

The concept and character arrived in Japan with the Chinese writing system; 時 appears in early Japanese texts and became central to timekeeping practices (civil, religious, and administrative) as Chinese calendrical notions and kanji use spread in the Asuka–Nara and Heian periods.

Composition

  • 日 (sun/day) — semantic element linked to cycles, daylight and the measurement of days.
  • 寺 (temple) — phonetic component; temples historically marked temporal divisions (bells, canonical hours), so combined the sign suggests ‘time’ when used as a whole.

Usage

Used across registers: in everyday speech the kun reading (toki) marks moments or ‘when’ clauses, while the on reading (ji) appears in numeric clock expressions and technical compounds; also found in formal writing, idioms, and set phrases to locate events temporally.
💡 Tips
Imagine a temple bell (寺) struck at sunrise (日) to mark the hour—that bell sound is 時 (toki): a moment or hour.

Variations

  • 時間 (jikan) — duration, amount of time
  • 時刻 (jikoku) — a clocked point in time
  • 頃 (koro) — approximate time/around
  • 刻 (koku / kizamu) — an old word for a short time interval or ‘to carve/measure time’
  • 永遠 (eien) — forever (conceptual antonym)
