With equal propriety we may say, “He offered no objection except the one already mentioned,” or “He read five books on ‘Crime and Its Causes’ in addition to those you named.” It is the use of the word other, or otherwise, or else, that makes necessary the correlative term than.
Besides
After else and other the preposition besides is sometimes employed.
“Other boys besides these are mischievous.”
“Other arts besides music are elevating and inspiring.”
