The word "more unassimilable" can be quite a mouthful, but it essentially means something that is more difficult or resistant to being absorbed or integrated. To find antonyms, we need to look for words that convey the opposite meaning. Therefore, potential antonyms could include "easily assimilable," "integrated," "absorbable," "ingestible," and "combinable." These words suggest that the thing in question is more receptive to being taken in or merged with other things, rather than resisting them. By understanding both the word and its antonyms, we can gain a better grasp of the concept of assimilation and how it operates in different contexts.
