How to say "language" in Japanese

Choosing the right word
  • 言葉ことばJLPT N5approx.Common
    nounLanguage in its everyday senses: what people speak, the words and expressions they use, and the dialect of a region or group. The word that comes naturally in daily conversation and writing.
    「言葉ことばの一面いちめんは、伝達でんたつしようとする意志いしである」と彼かれは言ゆう。↗
    "One aspect of language is an intent to communicate," he says.
  • 言語げんごJLPT N3approx.Common
    nounLanguage as a system: the word for language in the abstract — a human faculty, or a particular language such as Japanese or English — the term you meet in academic and technical writing.
    ドイツ語どいつごはやさしい言語げんごではありません。↗
    German is not an easy language.
  • ラングCommon
    nounSeldom the word you want for language in any ordinary sense: for that, 言葉 or 言語 is what a speaker uses. A katakana term learners can safely leave alone.
  • 言辞げんじCommon
    nounLanguage in the sense of speech or wording — what someone says and how they say it. It points to the expression of a particular speaker or statement, not to language as a system.
  • 言葉遣いことばづかいJLPT N2approx.Common
    nounLanguage as a person's manner of speaking: the wording and expressions someone uses, praised as polite or faulted as rough. It points to how something is said, not to language in general.
    言葉遣ことばづかいにはいつも気きをつけるべきです。↗
    You should always be careful in your speech.

Choose 言葉 for language in everyday talk, including a region's dialect, 言語 for language as a system, 言辞 and 「言葉遣い」 for wording and manner of speech, and leave 「ラング」 aside in ordinary use.
