expertise
UK: ˌɛkspɜːˈtiːz | US: ˌɛkspɜːrˈtiːz
n. specialized knowledge or skill in a particular field
n. the quality of being expert
The word "expertise" combines "expert," derived from Latin expertus (meaning "tried, tested, experienced"), with the French-derived suffix "-ise" (later Anglicized to "-ize" or "-ise"), which forms nouns indicating a state or condition. Originally used in French (expertise) to mean "judgment by experts," the term entered English in the 19th century to denote specialized skill or knowledge. The morpheme "expert" preserves its original spelling, while "-ise" marks the abstract noun form.
