In heraldry, arranged or positioned in the manner of a fesse; divided horizontally across the middle.
Formed from 'fesse' plus the adverbial suffix '-ly,' following the pattern of heraldic terminology from Old French and Latin roots.
Heraldic terminology created incredibly specific words to describe exactly how charges should be arranged—'fessely' is one of dozens of positional terms that allowed complex shield designs to be described precisely in text.
