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 means a live wire that is carrying electricity and can give you a shock if you touch it. So it refers to a wire that is 'carrying electricity' and therefore 'dangerous to touch'.
