Morphology

live + wire

The meaning 'an energized electrical conductor' is directly and transparently derived from combining 'live' (energized/charged) with 'wire' (a conductor); a B1 learner who knows both constituents can infer this literal sense. Although the phrase also has a metaphorical sense ('an energetic person'), the electrical meaning is compositional and cross-linguistically accessible.

Etymology

Live wire comes from the picture of a live wire that carries electricity, sparks, and is hard to touch. That's why a person called a live wire is 'full of energy' and always active.
