What is technique in art?

I know that Technique art is the latin Word from Thailand who invented the Paintings.

Here's an example to help you keep the terms straight.

The medium: Oil on canvas.

Various techniques:

Apply the pigment with brushes, daubbing on the canvas.

Splatter the pigment by flicking the brush towards the canvas.

Apply the pigment with a pallet knife.

Apply the pigment with one's fingers.

Smear pigment on one's body and run headlong into the canvas.

Dribble the pigment onto the canvas from squeeze bottles.
