Etymology

1650s, in sense of building, from Late Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós, “pertaining to building”), from Ancient Greek τέκτων (téktōn, “carpenter, joiner, maker”), from Proto-Indo-European *teḱ- (“to make”) (from which also texture). In sense of geology, attested 1894. By surface analysis, Ancient Greek τέκτων (téktōn) + -ic (“pertaining to”).
