IPA: //ˈsiːmliər//
KK: /ˈsimliər/
More appropriate or proper in appearance or behavior than something else.
Her outfit was seemlier than the others at the formal event.
Seemlier is formed from "seem" (from Old English "seman", meaning to appear or to be perceived) and the suffix "-lier" (a comparative suffix indicating more of a quality). The word "seemlier" means more apparent or more suitable in appearance.
Think of the word 'seem' which relates to how something appears, and the '-lier' indicates a comparison, so 'seemlier' means something that appears more suitable or fitting.
