Just in case you weren't sure what a ridiculous and complicated language English is, here are the six different pronounciations of the letter combination: ough.

'off' -- as in cough
'oo' -- as in through
'ow' -- as in bough
'uff' -- as in enough
'o' -- as in though
'aw' -- as in thought

Upon searching the net to double-check my submission, I found a site that claims the 'ough' sound in the word dough, is different than the sound in Scarborough. I can't hear the difference, but if I am wrong, please consider this the seventh pronounciation, and call me a moron.

The site also claims as an eighth sound 'up', as in the word hiccough. But I don't believe that to be linguisticly accurate. As I learned this, it was just the six sounds and no more. Again, if I'm wrong, please correct, and throw feces at me.

You're not a moron, just speaking the wrong dialect. The British English pronunciation of borough and compounds using it like Scarborough in Yorkshire and Loughborough (roughly Luff'-bruh) have a schwa as their final syllable, quite distinct from the sound in dough, toe, sew, mow, Po ...

The definitive list (southern British English):

1. Though - rhymes with so
2. Through - homophone with threw
3. Cough, Gough - rhyme with off
4. Tough, enough - rhyme with buff
5. Borough and its compounds, thorough - a short schwa
6. Hiccough - rhymes with up. I'd normally use the spelling "hiccup", though.
7. Bough - rhymes with cow (there exists also a surname pronounced as (3) above)
8. Ought, nought, fought, bought - rhyme with caught, taut, court, sort
9. Lough - homophone with loch

In at least some pronunciations of 'Scarborough' and like names, the 'ough' is simply a schwa sound (uh). (Scar-bur-uh)

My Merriam-Webster's Collegiate Dictionary, Tenth Edition lists this as the only pronunciation. But the online version at www.m-w.com has changed this to rhyme with dough.

A scan through other "ough" words on m-w.com reveals that this pronunciation is still there for Flamborough, Gainsborough, Poughkeepsie etc.

According to the pronunciation symbols used on www.m-w.com, the various pronunciations of ough (including some rarer ones) would be written:

1. of - cough
2. ü - through
3. au - bough
4. &f - enough
5. O - though
6. o - thought
7. & - Flamborough
8. &p - hiccough
9. äk or äk - lough
10. äf - Gough
11. ä - nought, ought

Note: for many people, ä is pronounced the same as o, so the last two probably shouldn't be counted as separate sounds.
