tectonic

Etymology

It is borrowed from Late Latin tectonicus,^[2][3][4][5] from Ancient Greek τεκτονικός (tektonikós, “pertaining to building”),^[2][5][3] from τέκτων (téktōn, “carpenter, builder”).^[2][6][7][8] Etymonline glosses téktōn also as a master of any art, such as sculpture, metalwork or writing, and derives it from Proto-Indo-European *teks- (“to weave, to fabricate”),^[3][4] and Barnhart and Klein relate it to τέχνη (tékhnē, “art, craft”).^[5][9]

Earliest recorded meaning

Of or relating to building or construction, used especially of architecture and related arts: 1656, in Thomas Blount's Glossographia.^[2][5][3]

Semantic evolution

The geological sense, relating to the structure of the earth's crust and the changes that affect it, is first recorded in 1894, in the Geological Magazine;^[2][5][7] Etymonline dates it to 1887.^[3] Barnhart thinks it came from the noun tectonics,^[5] which is recorded from 1850 for the constructive arts in general, in a translation of K. O. Müller's book on ancient art,^[2][5] and which the OED takes as an equivalent of Tektonik.^[2] Tectonics was used in geology from 1899.^[2][3] The adjective is also used of the crust of other planets and moons.^[2][10] From 1981 it has been used figuratively for a vast or momentous change, chiefly in tectonic shift.^[2]
