Word Origin & Etymology

Formed in English from the adjective 'adept' plus the native noun-forming suffix '-ness'. 'Adept' comes from Latin 'adeptus', the past participle of 'adipisci' ('to attain or acquire'), originally referring in medieval alchemy to a master who had attained the secret of transmuting base metals into gold.
