It's nearly always possible to translate the same word or phrase in different ways, as most things have slightly different meanings in other languages. The word 'cool' for instance, of course has the meaning of 'not very warm' as well as the typical meaning of 'good/great' etc. In fact 'cool' in the more modern meaning is quite hard to define as well as to translate. It does mean good, but in a very specific way - it also has meanings to do with looking good, impressing people, being in the fashion etc, which are so hard to convey that some languages, eg German, have adopted the word without trying to translate it.
