English Language divergent oddities
Obviously there's that one I pointed out ages ago:
crack shot = great shot
crack whore = terrible person
How about:
cat napping = fun little sleeps
kidnapping = stealing people
There's a certain parallel with the use of 'homo-' in our language since we use it in both:
Latin = man, e.g. homosapiens
Greek = uniform, e.g. homogeneous
Any other fun things?
