thematic

Etymology

The OED takes it as borrowed from Medieval Latin thematicus (“of or relating to a theme”), recorded from 1608 and in logic from 1612;^[2] most other dictionaries take it directly as borrowed from Ancient Greek θεματικός (thematikós).^{[3][4][5][6][7]} The Greek adjective, which in grammar meant primary, not derivative, is formed from θέμα (théma), the source of theme, and the suffix -ικός (-ikós).^[2][8][9] Greek théma meant a proposition or subject, literally something set down.^[3] The OED compares French thématique, recorded from 1572, in music from 1836 and of the stem of a word from 1872.^[2]

Earliest recorded meaning

In logic, designating the part of logic concerned with the subjects of thought: 1697, in a translation of Burgersdijck's Monitio Logica.^[2][3] This sense is now obsolete or historical.^[3][2]

Semantic evolution

After the logical sense of the 1690s, the word was taken up by music, where from 1825 it meant relating to a melodic theme or motif,^[2][4] and by grammar, where from 1845 it described the stem of a word and a vowel placed between the root and the ending.^[2][8][4] Historians used it from 1870 for the Byzantine system of military provinces called themes.^[2] The general sense, relating to the subject or underlying ideas of a writing or work of art, is recorded from 1871.^[2][3] In the 20th century it was used of stamps collected by subject (1949) and in linguistics of the part of a sentence that sets out its topic (1957); the noun thematics, the themes of a body of work, dates from 1957.^[2][10]
