Etymology

It is formed from English specialize + -ation.[2][3][4][5] The OED compares French spécialisation, recorded from 1830 and at first used of becoming a specialist in a particular kind of work or field of study.[2] Specialize is formed from special and -ize, perhaps on the model of spécialiser;[3][2] special comes from Old French especial and directly from Latin speciālis (“individual, particular”), from speciēs (“appearance, kind, sort”).[3] The British spelling is specialisation.[4][5]

Earliest recorded meaning

The action or process of making or becoming specialized, in work, an industry or a field of study: 1831, in the Quarterly Review.[2][3][4]

Semantic evolution

The noun spread from the division of work to language, ideas and legislation (1841).[2][6] Biology took it up for the way organisms and their parts take on a particular form or function in evolution or development: the OED's first record is from 1837,[2][6] while Etymonline dates the biological sense to 1862.[3] From 1865 it could also mean a feature produced by such adaptation.[2][7] In science and education it came by 1880 to mean the concentration of one's time and energy on one narrow field to the exclusion of others.[3]
