means A particular method or skilled way of doing something, especially one learned and refined through practice.

from From French technique, which leans on the Greek tekhnē, meaning 'art, craft, skill' — the same root that gives us technology and architect. The Greeks made little distinction between the artist and the craftsman: tekhnē was the know-how of making anything well, whether a sculpture or a sandal. The word arrived in English in the 19th century, carrying that ancient idea that mastery is a thing you can build.
