/ˌʌnɪksˈpaɪəd/ – adjective
Definition: 1. chưa hết hạn, chưa mãn hạn;
2. không chấm dứt hiệu lực vì hết hạn, vẫn còn có hiệu lực.
A more thorough explanation: “UNEXPIRED” refers to something that has not yet reached the end of its validity period or term, and therefore remains in effect or force.
Example: The tenant’s lease agreement is still in effect as it is unexpired for another six months.
