Insensibility to pain; the inability to perceive or feel pain; essentially another term for analgesia.
From Greek a- (without) + algos (pain) + -ia (condition). This is a more direct construction from the Greek roots than 'analgesia,' combining the pain-word more directly with the condition suffix.
You'll find 'analgia' in older medical texts alongside 'analgesia'—both mean the same thing, but 'analgia' is older and less common now. It's a reminder that medical terminology has evolved as languages standardized.
