1.) Extremely cold, cold as ice, icy, frosty. Also figurative.
2.) In a weaker sense: Cold, chill. Often of water, etc.: Refreshingly cold (Oxford English Dictionary 2nd Edition).
Etymology: adaptation of Latin gelidus, icy cold, from gelum (gelus, gelu) frost, intense cold.
"I prithee, Pru, abuse me enough, that's use me
As thou think'st fit; any coarse way, to humble me,
Or bring me home again, or Lovel on:
Thou dost not know my sufferings, what I feel,
My fires and fears are met: I burn and freeze,
My liver's one great coal, my heart shrunk up
With all the fibres, and the mass of blood
Within me is a standing lake of fire,
Curled with the cold wind of my gelid sighs,
That drive a drift of sleet through all my body,
And shoot a February through my veins."
(The New Inn, Ben Jonson, 1631)
