'abnormally-displayed' originates from the combination of 'abnormal' and 'displayed'. 'Abnormal' comes from Latin, specifically the word 'abnormis', where 'ab-' meant 'away from' and 'norma' meant 'rule'. 'Displayed' comes from Old French 'despleier', meaning 'to unfold'.

'abnormally-displayed' combines the adjective 'abnormal' with the past participle 'displayed', forming a compound adjective to describe something shown in an unusual manner.

Initially, 'abnormal' meant 'away from the rule', and 'displayed' meant 'unfolded'. Together, they describe something shown in a non-standard way.
