Morphology

dragline = drag + line (semi-transparent) = drag + line

The components 'drag' + 'line' are recognizable, but the specialized meaning 'large excavating machine' is a technical extension not immediately deducible by all learners.

Etymology

Dragline is simply drag + line, meaning a 'line' that 'drags'. It names the big digging machine because the machine uses a long cable or 'line' to pull a bucket and move earth.
