Meaning

A classical auxiliary adjective meaning 'like' or 'as if,' used to draw a comparison or simile. It indicates that something resembles or is similar to something else, carrying a literary and elevated tone.

ごとし is the classical equivalent of modern ～ようだ or ～みたいだ, but it conveys a far more literary, poetic, or solemn register. It conjugates as a classical ク-adjective: ごとく (adverbial), ごとき (attributive), ごとし (predicative). The pattern attaches to nouns with の or が, and to verbs in their dictionary or past form. It is frequently encountered in proverbs, literary works, formal speeches, and set expressions such as 光陰矢のごとし (time flies like an arrow). While rarely used in casual conversation, it remains productive in written Japanese, especially in journalism, academic prose, and ceremonial language. Compared to ～ようだ, ごとし implies a more dramatic or emphatic comparison.

Examples

1. 光陰矢のごとく過ぎ去り、気づけば十年が経っていた。 Time passed like an arrow, and before I knew it, ten years had gone by.
2. 彼の弁舌は滔々たる川の流れのごとく、聴衆を圧倒した。 His eloquence overwhelmed the audience like the flow of a mighty river.
3. 戦場は地獄のごとき様相を呈していたと、従軍記者は記している。 The battlefield presented a scene like hell, the war correspondent wrote.
