culture something (biology, medical) to grow a group of cells or bacteria for medical or scientific study Word Origin Middle English (denoting a cultivated piece of land): the noun from French culture or directly from Latin cultura ‘growing, cultivation’; the verb from obsolete French culturer or medieval Latin culturare, both based on Latin colere ‘tend, cultivate’ . In late Middle English the sense was ‘cultivation of the soil’ and from this (early 16th cent.), arose ‘cultivation (of the mind, faculties, or manners)’; sense (3) dates from the early 19th cent.
