costly
UK: ˈkɒstli | US: ˈkɔːstli
adj. expensive; involving high cost or sacrifice
adj. of poor quality despite high price
The word "costly" combines the noun "cost" (from Old French "cost," meaning "expense" or "price," ultimately derived from Latin "constare" – "to stand at a price") with the suffix "-ly," which forms adjectives indicating a characteristic (e.g., "friendly," "deadly"). Originally, "costly" emphasized the literal burden of expense, but over time, it also acquired connotations of excessive or unjustified cost, sometimes implying inferior value.
