〜ごとし / 〜ごとく (as though / like — literary comparison)

N1 grammar: classical auxiliary ごとし expressing literary simile ('like / as though'). Used in literary prose, proverbs, and formal descriptive writing.

〜ごとし / 〜ごとく

Formality Level: Literary / Formal — literary prose, proverbs, formal descriptions, classical quotations

Classical Origin: ごとし derives from classical Japanese gotoshi (如し), meaning "like" or "as." It appears throughout the oldest Japanese texts including the Manyoshu, the Kojiki (Record of Ancient Matters, 712 CE), and Nihon Shoki (720 CE). In Classical Chinese texts read in Japan (kanbun), the character 如 () expressed comparison. ごとし became the standard classical Japanese expression for simile and analogy. Its adverbial form ごとく (gotoku) and attributive form ごとき (gotoki) create literary comparisons that remain in use in formal modern Japanese prose.

Comparison with N2 Equivalent

Pattern Register Meaning Key Difference
〜ごとし/ごとく Literary/formal Like / as though (classical simile) Classical; literary elegance; used in proverbs, literary prose

When NOT to Use

  • Do not use ごとし/ごとく in casual conversation: These forms immediately signal literary register. In speech, ように or みたいに are appropriate.
  • Do not confuse ごとき with the particle ごとき meaning "such as" (derogatory): In modern spoken Japanese, そんなごとき can have a dismissive connotation ("the likes of"). The literary comparison form ごとき is different in usage and register.
  • Form requirement: ごとき (prenominal) modifies nouns; ごとく (adverbial) modifies verbs/adjectives; ごとし ends a clause. They are not interchangeable.
