Describing the impossible

[ignoramus]

Well, some things are impossible, at least in a definitional sense.  To take rob's first example, we define 'bachelor' as 'an unmarried adult male'.  Thus, a 'a married bachelor' is definitionally impossible.  Things of this sort are more than a labelling issue, they are a cognitive function issue.  The only way to make married bachelors possible is to redefine 'married', 'bachelor' and 'impossible'. Until and unless we are willing to do so, a married bachelor is, in every sense that matters, an impossibility.  Others:

-Canine cats

-Arctic tropics

-Wet desert

-Uneaten meal

-Non-alcoholic ethanol

Boru

Agree with the last one. Boru can be impossible at times!
