Stroke Order

Meanings

  • natural state or condition — shizen no joutai
  • natural materials or products — tennen sozai
  • unplanned or spontaneous behavior — shizen na koudou
  • airhead, ditzy person in casual slang — tennen-boke

Etymology

on’yomi ten and nen combine to form tennen, a Sino-Japanese reading that yields 天然; the compound arose as a lexical unit in Japanese via kanji adoption and took the meaning of natural or unmodified over time.

Origin

Adopted from Chinese 天然; used in Sino-Japanese literature, the term broadened in modern Japanese to cover natural materials, natural states, and natural behavior.

Composition

  • 天 = heaven, sky; contributes sense of natural domain
  • 然 = natural, thus; indicates a natural state or occurrence
  • Combination yields 天然, meaning a state or thing that exists in nature without human modification

Usage

Used as a noun; 天然の attaches to nouns to mean natural or authentic material or condition; in everyday speech 天然だ or 天然の人で describe someone as ditzy or spacey in casual talk; in formal writing it can describe inherent or natural characteristics without implying artificiality.
💡 Tips
Mnemonic: visualize the sky (天) blessing nature, and 然 signaling a natural state; together they cue the sense of things as they occur in nature, not engineered.

Variations

  • 自然の — natural (shizen no)
  • 人工的 — artificial (jinkouteki)
