How to say "translation" in Japanese

Choosing the right word
  • 翻訳ほんやくJLPT N4approx.Common
    noun, suru verb, transitive verbThe general word for translation — rendering a text from one language into another, whether the act or the resulting work. This is the usual choice in everyday contexts.
    彼女かのじょはそれを一いち語ご一いち語ご翻訳ほんやくした。↗
    She translated it word for word.
  • 訳書やくしょCommon
    nounA translated book: the finished work as a publication rather than the act of translating. Use it when 'translation' means an actual translated book.
  • 訳文やくぶんCommon
    nounThe translated text itself — a sentence or passage as rendered in the other language, rather than the act or the book. Also used of a particular version of a translated passage.
    君きみたちの訳文やくぶんと黒板こくばんの訳わけを比較ひかくしなさい。↗
    Compare your translation with the one on the blackboard.
  • 訳語やくごCommon
    nounThe equivalent word chosen for a particular word in translation — a single-word rendering or gloss. Not for translating whole texts; it concerns how one word is translated.
  • 換算かんさんJLPT N1approx.Common
    noun, suru verb, transitive verbNot language translation at all: conversion of figures, as in changing yen into dollars. Choose it only when English 'translation' refers to converting numbers or units.
    あなたは何なんでも金かねに換算かんさんして考かんがえない方ほうがよい。↗
    You had better not think of everything in terms of money.

Use 翻訳 for translation in general; 訳書 for a translated book, 訳文 for a translated passage, 訳語 for an equivalent word, and 換算 only for converting numbers, never for translating between languages.
