～が～なら

• 読み: がなら
• ローマ字: ga nara
• 形: Noun A + が + Noun A + なら + Noun B + も + Noun B（+ だ）

意味

A structure used to present two parallel qualities or shortcomings, meaning 'if A is like that, then B is also like that.' It implies that both parties share responsibility or exhibit similarly notable traits.

～が～なら～も～だ draws a parallel between two entities, emphasising that both are equally notable, most commonly in a negative or critical sense. The classic form is 親が親なら子も子だ (if the parents are like that, the children are like that too). While most commonly used critically, it can appear in neutral or positive contexts highlighting matching qualities. The structure differs from simply using なら as a logical conditional because it does not set up an if-then consequence; rather, it pairs two subjects as equally remarkable. Learners sometimes confuse it with the pure conditional ならば or the concessive にしても, but ～が～なら uniquely frames two matched entities as cut from the same cloth.

正しい言い方

• 監督が監督なら選手も選手で、チーム全体に緊張感がない。
• 兄が兄なら弟も弟で、二人とも約束を守らない。
• 店長が店長ならスタッフもスタッフで、接客態度がひどい。

避ける言い方

• 親が親だったら子も子だ。(Using だったら instead of なら — this set phrase requires なら to create the parallel structure) → 親が親なら子も子だ。
• 親は親なら子も子だ。(Using は instead of が — the pattern requires が to mark the first noun as the subject of evaluation) → 親が親なら子も子だ。

起源と歴史

Built on the conditional なら and the subject marker が. The structure mirrors a broader Japanese rhetorical device of parallel enumeration, where repeating the same noun on both sides emphasises the inseparable similarity of the two parties.
