means Happening in real time, broadcast or performed as it occurs rather than recorded for later; also, the adjective form meaning alive or carrying current.

from From Old English 'libban/lifian,' to live, tied to 'lif' (life) and rooted in a Proto-Germanic verb shared with German 'leben' and a deeper Proto-Indo-European sense of sticking, persisting, remaining. The adjective 'live' — as in 'live wire' or 'live broadcast' — is the younger sibling, a clipped form of 'alive' that emerged only a few centuries ago; the meaning 'transmitted as it happens' is younger still, arriving with the age of radio and television.
