Bannered → It is formed from "banner" (from Old French *baner*, meaning a flag or standard) and "-ed" (a suffix indicating past tense or a completed action). The word "bannered" means having been marked or decorated with a banner.
Think of a flag or standard ('banner') that has been used or displayed ('-ed') — that's why 'bannered' means marked with a banner.
