The word "coolness" derives from the Old English "cōl," meaning "moderately cold" or "calm," which traces back to Proto-Germanic *kōlaz. The suffix "-ness," of Old English origin, transforms adjectives into nouns denoting a state or quality. Over time, "cool" expanded semantically to include emotional composure and later, slang for stylishness (mid-20th century). "Coolness" thus encapsulates physical, emotional, and cultural dimensions of its root.
