336: diarrhea Nov 9, 2015

The word 'diarrhea' (alternatively the British 'diarrhoea') is a commonly misspelled word. It ultimately comes from the Greek word 'diarrhoia', which is a contraction of 'dia' meaning ‘through’ and 'rhein' meaning ‘to flow’, for obvious reasons. The double 'r', 'h' combination that usually gives spellers some trouble is typical of English's Greek-borrowed words.
