I could not find a good definition of the word, cool, so I made up my own.
Swedes worry when they say “kul” meaning fun or funny, people will think they mean cool. Cool has come to mean “quite pleasantly acceptable in the current social context”, but dictionaries generally claim ignorance of what it really means. In Danish, kul derives from Old Norse, “kol”, meaning coal in both languages. Based on the old Anglo-Saxon meaning, English, as well as,in German, “kühl“, and Dutch, “ koel”, it still has the meaning of a “pleasantly low temperature” as distinct from chilly. In French, “col”, means col from the Latin word, “collum” meaning neck. When the word, “cool” appears in French or Swedish text, it means the English word.
