Colloquial interjection expressing surprise, disbelief, or shock. Usually written うそ or ウソ in casual dialogue.
ウソ、もう売り切れたの？
No way, it's already sold out?
うそ！本当に合格したの？
Really?! Did you actually pass?
Common kana spelling in casual or learner-facing writing.
Means truth, reality, or genuine; it is the basic opposite of 嘘 in the main sense.
The ordinary word for a mistake or error; unlike 嘘, it does not suggest deception and is usually the safer choice for errors.
Means falsehood or deceit in a more formal or literary style; 嘘 is the everyday conversational word.
The historical derivation of うそ is uncertain. 嘘 is the conventional kanji spelling associated with lying or falsehood; the kana and katakana spellings are also common in everyday use.
