Kanji 無 nothingness, none, ain't Related words 間違いない can stand alone as "that's certain/right," while 違いない is mainly used in the pattern に違いない to express strong inference.
きっと is an adverb meaning "surely/probably" that softens a prediction, whereas 違いない (usually に違いない) asserts a firmer, near-certain conclusion.
Politeness 相違ない is the formal, written counterpart of 違いない, both meaning "there is no doubt," but 違いない is far more common in everyday speech.
Written forms 違ちが いない
Standard mixed kanji-kana spelling; common both as a predicate and in the pattern に違いない.
違ちが い 無な い
Kanji-heavy variant using 無い; understandable but less typical in ordinary writing than 違いない.
Etymology Composed transparently from 違い, “difference; mistake,” plus ない, “not exist,” giving the idea that there is no mistake or no room for a different conclusion. This is a semantic explanation, not a claim about a separate historical origin.
