Incorrect spelling


Incorrect spelling, explanation: it may seem that the word summary comes from the base word sum, so it should be spelled sumary, but it’s incorrect. In fact, the word sum with one m is based on the Latin summa. The second m is useless in the shortened English word sum, but it is necessary to keep it in summary.
