- Takes a NOUN (or 〜から for the reason form). It asserts an exact identification, ruling out any other explanation — not a tentative guess.
Easily confused with
に過ぎない にほかならない affirms 'is precisely / nothing but X' (emphatic, often weighty); に過ぎない deflates 'is merely / no more than X' (dismissive). Opposite valence on the same 'nothing but' frame. に違いない に違いない is a confident conjecture about something uncertain ('must be'); にほかならない is a definitive identification of equivalence ('is precisely'), not a guess.
