Etymology: The "hot" in hotline is the ordinary adjective, but its ancestry runs back through Old English "hāt" to a Proto-Germanic word for heat, which is also the root of the English adjective used for anything glowing or scalding. The "line" half has a longer and more tangled path. It descends from Latin "linea", meaning a linen thread (from "linum", flax), and reached English through Old English "līne", then reshaped by Middle French "ligne" and Middle English "line", so the word that once named a flax cord now names a wire. Put together, hot plus line describes a telephone connection that is always open between two points, so that a call can be made without dialing. The compound is transparent: nothing in it required a special coinage, and its meaning follows directly from the two parts. The word belongs to the same family as "hotbed" and "hot seat", where "hot" signals urgency or immediacy rather than temperature.
