IPA: //ʌnˈstɪtʃt//
KK: /ʌnˈstɪtʃt/
Describing something that has not been sewn together or is coming apart at the seams.
The unstitched fabric was difficult to work with for the sewing project.
Unstitched → It is formed from "un-" (meaning not) and "stitched" (from Old English "stician", meaning to pierce or sew). The word "unstitched" means not sewn or having been taken apart from stitches.
Think of something that is 'not sewn' ('un-') — that's what unstitched means.
