Nimaijita (二枚舌 - Double Tongue)

There are several Japanese expressions that means to tell a lie.

The term "nimaijita" (二枚舌) is one of them.

The "nimai" (二枚) means "two pieces," and the "jita/shita" (舌) means "tongue," so the literal meaning of "nimaijita" is "two tongues."

However, this term is used to mean that someone tells a lie or say contradictory things.

Since people who say lies or contradictions fluently are as if they have two tongues and each one says different things, this term has come to be used.

Incidentally, today I learned English has a similar expression -- "speaking with a forked tongue" means to tell a lie.

二枚舌

嘘をつくことを意味する表現はさまざまあります。

「二枚舌」もその一つです。

「二枚舌」の文字どおりの意味は「二枚の舌」ですが、実際には嘘をつことや、矛盾したことを言うという意味で使われます。

平気で嘘や矛盾したことを言う人は、口の中に二枚の舌があり、それぞれ違ったことを言っているようであることから、この言葉が使われるようになりました。

英語でも同じように "speaking with a forked tongue" （枝分かれした舌で話す）と言うと、嘘をつくという意味になります。
