"Pothole" is one of those English words that defies pronunciation standards. If you didn't know it was "pot-hole", you'd think it was "poth-ole". I first came across this phenomenon at school when we were each given a dictionary and asked to find words with the consecutive letters "ph" in them, and one of the girls produced "shepherd". I myself had simply looked up words beginning with "ph" so got rather more of them than she did, but I was still impressed. In the 1980s, people referred to Clapham as "Claffam" as a joke to complain about gentrification.
That's one deep pothole. A tractor could lose a tyre if it drove through that.
