IPA: //ʌnˈkɜːrtənd//
KK: /ʌnˈkɜrtənd/
Describing a space or area that does not have curtains covering the windows or openings.
The room felt bright and open because it was uncurtained.
Uncurtained → It is formed from "un-" (meaning not) and "curtain" (from Old French *cortine*, meaning a hanging screen or drapery). The word "uncurtained" means not having a curtain or being without a curtain.
Think of 'not' ('un-') having a 'hanging screen' ('curtain') — that's why uncurtained means without a curtain.
