IPA: /ˈtrʌmpəri/
KK: /ˈtrʌmpəri/
Something that is showy but has no real value; often refers to deceptive or worthless items or ideas.
The market was filled with trumpery that no one wanted to buy.
Trumpery originates from the Middle English 'trumpery' (meaning worthless or deceitful things), which is derived from the Old French 'tromper' (meaning to deceive). The word refers to things that are showy but worthless or deceptive in nature.
Think of 'deceiving' ('tromper') things that appear attractive but are actually worthless — that's what trumpery means.
