Meaning & usage
なぜなら(ば) introduces a separate sentence that explains the cause or reason for what was stated before, corresponding to because or the reason is that. It appears at the start of the reason sentence, which must close with からだ or polite からです attached to the plain form. Nouns and な-adjectives take だからだ, as in 学生だからだ, while verbs and い-adjectives attach directly. The pattern is formal and common in writing and explanations, and omitting からだ makes the structure incomplete.
