specialize

the word 'specialize' is built upon the core latin root 'species', which originally conveyed the notion of 'appearance', 'form', or 'kind'. the addition of the adjectival suffix '-al' created 'special', meaning 'of a particular kind' or 'distinct'. the final layer, the verb-forming suffix '-ize', was later appended, a productive suffix borrowed from greek via latin that means 'to make' or 'to become'. thus, the etymological logic flows from the concept of a distinct type, to the adjective describing that type, and finally to the verb meaning 'to make oneself of a particular type' or 'to focus on a specific area', capturing both its academic and biological senses.
