〜じゃない

〜じゃない is part of the copula system in Japanese, expressing is not (casual). The copula connects subjects to descriptions or identifications, similar to "is/am/are" in English, though Japanese copula expressions work quite differently from their English counterparts.

This is a foundational pattern that you will use from day one of your Japanese studies.

When to Use#

• When casually negating an identity or description
• When saying something is not the case in informal speech

When NOT to Use#

Common Mistakes#

1. Direct translation from English — The concept expressed by 〜じゃない may not map one-to-one with its English translation. Focus on understanding the Japanese usage through example sentences rather than relying on the English gloss.
