foiled

the word 'foiled' originates from the verb 'foil', which entered english in the 14th century from old french fuler, meaning 'to trample underfoot' or 'to full cloth'. this french term has germanic roots, likely connected to a notion of flattening or beating. the sense of 'thwarting' or 'frustrating' developed metaphorically from this literal idea of trampling something down, preventing its rise or success. the '-ed' suffix, a common germanic participial ending, attaches to form the past tense and the adjective, describing the state of having been thwarted or, in a separate decorative arts sense, of having been worked into a patterned, laminated sheet.

Structure: foil + ed foil (from old french fuler, 'to trample, full cloth', of germanic origin; verb base meaning 'to frustrate or prevent') + ed (from old english -od/-ad; suffix forming past tense and past participles of verbs, or adjectives from verbs)
