technologist (n.)

1610s, "a discourse or treatise on an art or the arts," from Latinized form of Greek tekhnologia "systematic treatment of an art, craft, or technique," originally referring to grammar, from tekhno-, combining form of tekhnē "art, skill, craft in work; method, system, an art, a system or method of making or doing," from PIE *teks-na- "craft" (of weaving or fabricating), from suffixed form of root *teks- "to weave," also "to fabricate." For ending, see -logy.

The meaning "study of mechanical and industrial arts" (Century Dictionary, 1895, gives as examples "spinning, metal-working, or brewing") is recorded by 1859. High technology is attested by 1964; short form high-tech by 1972.

word-forming element meaning "one who does or makes," also used to indicate adherence to a certain doctrine or custom, from French -iste and directly from Latin -ista (source also of Spanish, Portuguese, Italian -ista), from Greek agent-noun ending -istes, which is from -is-, ending of the stem of verbs in -izein, + agential suffix -tes.

Variant -ister (as in chorister, barrister) is from Old French -istre, on false analogy of ministre. Variant -ista is from Spanish, popularized in American English 1970s by names of Latin-American revolutionary movements.
