Etymology: "Unwarm" is a plain formation: the prefix "un-", meaning "not", attached to the adjective "warm." The result describes something that is not warm, whether that means cool, lukewarm, or simply lacking heat. The prefix is the older and more productive part of the story. "Un-" comes from Old English "un-," which was used to make negative or reversing forms of words, and English has long attached it freely to adjectives, so new negations can be built on demand. "Warm" itself is a native English word, descending from Old English "wearm," which has the same core sense of heat. Because "unwarm" is a transparent combination of two familiar parts, it carries no hidden surprise: its meaning can be read directly from its pieces.
