Etymology: "Uncooler" is the comparative of "uncool", so it is "more uncool" in a single word. The base word "uncool" joins the prefix "un-", meaning "not", to "cool", which English has used since Old English "cōl", meaning "cool" in the sense of temperature. The sense of "cool" as fashionable or stylish came much later, and it is that social meaning that "uncool" negates. The prefix itself is very old. "Un-" descends from Proto-Germanic and was used in Old English to reverse adjectives, so English speakers could attach it to almost any description and get its opposite. That is why the form is so easy to build: "uncool" is a straightforward negation, and "uncooler" simply adds the comparative ending "-er" to it, as with "cooler" and "bigger".
