About に相違ない

In a similar fashion to に(ちが)いない, 相違(そうい)ない is a structure that firmly states that something is 'without a doubt (A)', or that there is 'no mistaking (A)'. It may be used to strengthen one's own opinions, or to strongly agree with the opinion of another. Although 相違(そうい) may be used by itself meaning 'to differ', or 'to have a discrepancy', 相違(そうい)ない is considered as a set い-Adjective. When combined with ない, the literal meaning is just 'there is no discrepancy in (A)'.

相違(そうい)ない may be used with verbs, い-Adjectives, な-Adjectives and nouns.

に相違ない will often follow から, highlighting that there is no mistaking the 'cause' of (A).

Caution

This grammar structure is very formal, with に(ちが)いない almost always being used in its place.
