The antonyms for the phrase "more altogether" can vary depending on the context in which it is used. However, some possible antonyms include "less individually," "fewer in total," or "minimal as a whole." These antonyms imply a reduction in quantity or quality, as opposed to an increase or expansion. For instance, the phrase "less individually" might be used to describe a group where each member contributes less, while "fewer in total" can reference a smaller number of items or people. On the other hand, "minimal as a whole" could suggest a situation where the collective impact is negligible or insignificant.
