Definition and meanings of “kuchi”

Let me start with the definition and meanings of “kuchi”.

• kuchi – 口 (くち) : a noun meaning ‘mouth’ in Japanese. This can also work as a plural noun. Learn more about Japanese plural.

Japanese native speakers normally use this noun to refer to someone’s mouth. Sometimes, however, they use it as a metaphor for a hole, gate, opening, exit, or even the act of speaking. Knowing this usage would help Japanese learners to better understand real Japanese conversations.

The kanji character of “kuchi” originally came from the shape of a mouth. Honestly, it looks more similar to a rectangle, but this is the origin of this kanji.

The definition and meanings are not so difficult, I think. Then, let me explain how to use “kuchi” through the example sentences below.

Example #1: how to say “mouth” in Japanese

Below are the new words used in the example sentence.

• watashi – 私 (わたし) : a pronoun meaning ‘I’ in Japanese.
• no – の : a case particle used after a noun or pronoun to make its possessive case. In the example, this is used after “watashi” to make its possessive case, “watashi no“, which means ‘my’ in Japanese.
• wa – は : a binding particle working as a case marker or topic marker. In the example, this works after “watashi no kuchi” to make the subject in the sentence.
• chiisai – 小さい (ちいさい) : an i-adjective meaning ‘small’ in Japanese.
• desu – です : an auxiliary verb used after a noun or adjective to make it polite. Probably, this is well known as a part of Japanese desu form. In the example, this is used after “chiisai” to make it sound polite.

This is a typical usage of “kuchi”. In the example, it works as a part of the noun phrase, “watashi no kuchi”, which means ‘my mouth’ in Japanese.

Example #2: another usage of “kuchi”

Below are the new words used in the example sentence.

• shinin – 死人 (しにん) : a noun meaning ‘dead man’ in Japanese. This can also work as a plural.
• ni – に : a case particle used to indicate where someone or something is. In the example, this is used after “shinin” to indicate where no mouth is.
• nashi – なし : one conjugation of the i-adjective, “nai“, which is used to deny the existence of things in Japanese. In the example, this is used to deny the existence of a mouth.
• to – と : a case particle working as a quote marker. In the example, this works after “shinin ni kuchi nashi” to indicate what he said.
• kare – 彼 (かれ) : a pronoun meaning ‘he’ in Japanese.
• ga – が : a case particle used to make the subject word or the object word in a sentence. In the example, this is used after “kare” to make the subject in the sentence.
• it – 言っ (いっ) : one conjugation of the verb, “iu”, which means ‘to say’, ‘to tell’, or such in Japanese. In the example, it has been conjugated for the better connection with its following word.
• ta – た : an auxiliary verb used after a verb, adjective, or auxiliary verb to make its past tense form. In the example, this is used after “it” to make its past tense form, “it ta”.

This is another typical usage of “kuchi”. In the example, it works as a part of the Japanese proverb which has the same meaning as the English one, “dead men tell no tales”. The literal interpretation of the Japanese one is more like “no mouth exists on the dead men (or the dead men’s faces)”, but it’s normally translated as ‘dead men tell no tales’.
