Definition

According to the Liddell-Scott-Jones Lexicon, καῦσος is "burning heat, fever." It is a noun derived from the Ancient Greek verb καίω ("to burn, to set on fire") and denotes a state of intense heat, whether physical or pathological. In classical Greek medicine, particularly in the works of Hippocrates, καῦσος frequently refers to a specific type of fever, characterized by continuous and intense heat, often accompanied by thirst and dryness.

The concept of καῦσος was not limited solely to fever but extended to other inflammatory conditions or ailments causing a burning sensation, such as herpes (καῦσος ἕρπης). Galen, later, further analyzed καῦσος as an expression of an imbalance in the body's humors, where excessive bile was often considered the cause of the internal "burning."

Beyond its medical use, καῦσος could generally describe intense heat, such as that of the sun or fire, although in this context, the related noun καῦμα was more frequently used. Its predominant meaning, however, remained in the medical field, as a term for fever and inflammation.

Etymology

καῦσος ← καίω ← καυ- (Ancient Greek root belonging to the oldest stratum of the language)
The word καῦσος derives directly from the Ancient Greek verb καίω, meaning "to burn, to ignite, to heat." The root καυ- is a fundamental root in the Greek language, expressing the concept of heat and combustion. The transformation of the verb into a noun with the suffix -σος indicates the state or result of the verb's action, i.e., "burning" or a "heated state."

From the same root καυ- derive many words related to fire, heat, and burning. Examples include the noun καῦμα ("burning, heat"), the adjective καυστικός ("burning, corrosive"), the verb ἐκκαίω ("to burn out completely, to ignite"), and the noun ἔγκαυμα ("a burn, a mark from burning"). These words highlight the productivity of the root in describing various aspects of thermal energy and its consequences.

Main Meanings

  1. Intense Heat, Burning — The general meaning of combustion or intense heat, such as that caused by the sun or fire.

  4. Inflammatory Disease — Specific diseases characterized by inflammation and heat, e.g., herpes.
  5. Destruction by Fire — More rarely, the destruction caused by a conflagration.
  6. Heat of Passion — Metaphorical use for the intense heat or flame of a passion or emotion.
