History and Etymology for tectonic

probably borrowed from German tektonisch "pertaining to broader structural features of the earth's crust," earlier "of building or construction," borrowed from Late Latin tectonicus "of a builder or architect," borrowed from Greek tektonikós "of a carpenter, skilled in carpentry or building," from tekton-, téktōn "woodworker, carpenter, craftsman" + -ikos -ic entry 1; téktōn going back to Indo-European *tetḱ-on- (whence also Sanskrit takṣan-, tákṣā "carpenter," Avestan tašan-, tašā "builder, creator"), n-stem derivative from a verbal base *tetḱ- "fashion, produce," whence Sanskrit tákṣati "(s/he) fashions, builds from wood," Avestan tāšt "(s/he) forms," Latvian tešu, tèst "to hew," Old Church Slavic tešǫ, tesati "to hew, fell," (with o-grade) Lithuanian tašýti "to hew"

Note: A root of the form *tetḱ- would be peculiar for Indo-European. Helmut Rix, et al., (Lexikon der indogermanischen Verben, 2. Ausgabe, Wiesbaden, 2001) rescue the situation by hypothesizing that *tetḱ- represents a pre-Indo-European reduplicated aorist, *te-tḱ-, of a root *teḱ-, seen in unreduplicated form in Greek téknon "child, young of an animal" and étekon, tekeîn, aorist of tíktō, tíktein "to give birth to, beget, generate" (see dystocia). However—aside from the certain correspondence of Greek téktōn with Vedic Sanskrit takṣan-, Avestan tašan- —all other outcomes of this supposed root can be accounted for as *teḱ-s-, an extended form of *teḱ-. To explain this anomaly, Andrew Sihler (New Comparative Grammar of Greek and Latin, Oxford, 1995, p. 225) hypothesizes that téktōn is a conflation of a regular derivative *texōn and an unattested agentive derivative *téktōr, going back to *teks-tor-, (with cluster simplification as in hektós "sixth" corresponding to héx "six"). Traditionally added to the compared forms given in the etymology above are Latin texere "to weave, form by plaiting or twining, construct" and other words (see at text entry 1). See also technical entry 1.
