The governers of a private school have reluctantly concluded that the annual tuition fee will have to be increased, so the headmaster dictates a letter to parents advising them of the unwelcome news. Unfortunately, the headmaster's secretary, a young lady who has had the benefit of a modern British public-sector education, mistypes the phrase per annum as per anum and this misspelling goes under the radar of her trusty spell checker.
A bemused and irritated parent writes back
While I reluctantly accept the inevitably of this increase in my son's fees, I fear I must dissent from your proposed method of payment. I shall continue to pay per nasum as usual.
(Crib for those who haven't had the benefit of a classical education at a pretentious school like wot I have, here, here and here.)
