technical: [17] Greek tékhnē denoted ‘skill, art, craft, trade’ (it may have come from the Indo- European base *tek- ‘shape, make’, which also produced Greek téktōn ‘carpenter, builder’, source of English architect and tectonic [17]). From it was derived the adjective tekhnikós, which passed into English via Latin technicus as technic (now obsolete) and technical. Technique [19] comes from a noun use of the French adjective technique ‘technical’. From the same source come technicolour [20], based on the trademark Technicolor (registered in 1929), and technology [17].
