1.
simile; explicit comparison
A figure of speech that directly compares two things using words like 'like' or 'as' (in Japanese, ような, みたいな, のごとく). Contrasts with 隠喩 (metaphor).
Usage
直喩 is a literary and grammatical term. In Japanese, similes typically use ~のような, ~みたいな, ~のごとく, or ~のように to make the comparison explicit.
Similar words
隠喩 (metaphor) is the counterpart — an implicit comparison without using comparison words. Example: 直喩: 「彼女は花のように美しい」(She is beautiful like a flower). 隠喩: 「彼女は花だ」(She is a flower).
Forms
直 (direct) + 喩 (comparison/metaphor).
