intellectual
UK: ˌɪntəˈlektʃuəl | US: ˌɪntəˈlektʃuəl
adj. relating to the intellect or mental capacity
n. a person possessing highly developed intellectual abilities
The word "intellectual" derives from the Latin intellectus (understanding, perception), formed from intellegere (to understand), itself combining inter- (between) and legere (to gather, choose). The suffix -ual (from Latin -alis) denotes relation, creating the sense of "pertaining to the mind." Historically, it evolved in Medieval Latin as intellectualis, entering English via Old French in the 14th century to describe rational or learned qualities.
