Sorry, I thought it'd be obvious that all those -ough words have different pronunciations (for most people, anyway, I think) and that I'd be making my point clearly and lightheartedly. I was just saying that English spelling isn't always "guessable", or how you think it logically should be. [Even though it may well be guessable the majority of the time, as another responder points out, for some reason].

The fact you think "busses" is a preferable spelling to "buses" because it might help you pronounce "buses" differently to "fuses" is only relevant to you yourself. I would have thought this was tautological, myself.

In summary, we could avoid all these fusses with a bit of effort to adhere to accepted usage.
