the invisible co-conspirator that turns 80 degrees into a personal hostage situation
means The amount of water vapor present in the air, which determines how muggy, sticky, or damp it feels.
from From Latin 'humidus,' meaning 'moist' or 'wet,' which grew from the verb 'humere,' 'to be moist.' It traveled into English through Old French 'humidite' and settled in by the late 1300s. The Latin root is also a distant relative of 'humor' — back when 'humor' meant a bodily fluid rather than a joke, both leaned on that same notion of dampness and flow.
