What does sthenic mean?
Sthenic is a rare adjective meaning strong, vigorous, or robust, especially in reference to a person’s health or physiological activity. In medical contexts, it can describe a condition or response marked by considerable intensity and energy rather than weakness or decline. The word is formal and technical, so ordinary speakers are more likely to use strong, vigorous, robust, or energetic. Its contrast with asthenic is particularly useful: asthenic refers to weakness or reduced vitality, while sthenic emphasizes strength and force. Although uncommon in everyday English, sthenic remains useful in medical writing because it can distinguish a robust or highly energetic physiological state from a depleted one. The adjective comes from the Greek root sthenos, meaning strength, which also underlies the contrasting term asthenic.
