Being noncommensurate is the antonym for being commensurate. Noncommensurate means not equivalent or not proportionate in size or degree. Another antonym for commensurate is disproportionate, which means that something is not in balance or the right proportion. Furthermore, unequal, imbalanced or inadequate can also be used as antonyms for commensurate. When something is commensurate, it is aligned or in congruence, indicating a proper balance or justice. In contrast, the antonyms for commensurate indicate that something is either too much or too little, creating an imbalance or injustice in the situation. Therefore, it is essential to use the right antonym for the right context to convey the intended meaning precisely.
