| Usage notes | Use 'altogether' when you want to emphasize a total amount. Avoid in very formal writing; 'in total' might be better. | Use 'completely' to emphasize the totality of an action or state. It's suitable for both spoken and written English but might sound overemphasized in casual conversation. |
