Etymology
The word 'drag' originates from the Old English verb 'dragan', meaning "to draw, pull, or drag." This, in turn, can be traced back to the Proto-Germanic 'draganą' and further to the Proto-Indo-European root 'dʰreǵʰ-', which carried the sense of "to pull, draw, or carry." The semantic journey from the concrete, physical action of pulling a heavy object across the ground to its modern abstract meanings is a clear example of metaphorical extension. The sense of something being a hindrance or "drag" derives from the idea of a literal weight that slows movement. The computing sense, emerging in the late 20th century, is a specialized application of the core pulling action, now applied to a virtual object on a graphical interface.

This is a simplex word of Old English origin. The core morpheme 'drag' functions as a root verb, with its related noun forms derived through functional shift (conversion).
