Used in casual conversation. More informal than はい.
Use ええ in casual settings with friends or family. In formal situations, prefer はい or そうです.
From Old Japanese え (e), a particle expressing agreement or affirmation. Evolved into modern ええ (ee) in the Edo period.
ええ is softer and more casual than はい. It can sound overly familiar in formal settings. In some regions (e.g., Kansai), ええ is used more frequently than in standard Tokyo dialect.
