À propos de ならいざ知らず

ならいざ知(し)らず is a grammar expression which combines the hypothetical form of the auxiliary verb だ, なら, the adverb いざ ‘now’, or ‘well then’, and the classically-negated form of the う-Verb 知(し)る, 知(し)らず ‘to not know’. It is often translated as ‘I don’t know about (A), but (B)’, or ‘maybe (A), but (B). This phrase is formal, and usually used to emphasize that, regardless of (A), (B) fits a specific description.

ならいざ知(し)らず will follow verbs in their standard forms. Additionally, it may follow either な-Adjectives or nouns that have had their terminal だ replaced with なら.

Just like the literal translation of ‘if it’s (A), well then I don’t know’, this structure emphasizes that (A) may or may not be the case, but (B) is definite. However, there is no direct use of ‘but’ in Japanese. This shows that the ‘but’ comes from the simple contrast of (A) being unknown while (B) is known.

ならいざ知(し)らず may also be seen following other structures such as い-Adjectives when they have been nominalized with の.

This の pattern is also used with verbs, but it is less common than simply attaching ならいざしらず to one of the standard verb forms.

Fun Fact

In many cases, (A) is an extreme example used to show that (B) is the opposite of that, and is therefore either surprising or irritating.

Caution

Occasionally は will be used instead of なら. However, the meaning of the overall phrase will remain the same.
