ough and ought ending words

It's hard to believe that words ending in ough and ought can have EIGHT different pronunciations!
This exercise uses 5 of the 8 pronunciations.

Here is a list of SOME of these words, which I consider you are most likely to encounter.
although
bough
bought
brought
cough
dough   
drought
enough
fought
hiccough
nought  
ought
plough
rough
sought
thorough
though
thought
through
tough
trough   
It's worth putting them into groups by pronunciation, AND writing the phonetics for the complete words.
