に加えて

に加えて is used to add information that supplements what has already been mentioned. It introduces an additional element or factor, similar to 'in addition to' or 'not to mention'. It often comes after a noun, verb, or adjective to indicate that another item or aspect is being added to the list of considerations. This grammar emphasizes the added importance or contrast between the first item and the new one. It can convey both a neutral addition or a stronger sense of surprise or emphasis, depending on context.
