IPA: //ʌnəˈmɛndɪd//
KK: /ʌnəˈmɛndɪd/
Describing something that has not been changed or modified in any way.
The contract remained unamended despite the discussions.
Unamended → It is formed from "un-" (meaning not) and "amend" (from Latin "emendare", meaning to correct or improve). The word "unamended" means not corrected or improved.
Think of 'not' ('un-') having been 'corrected' ('amend') — that's why unamended means something that hasn't been improved.
