What does it mean if two things are 'commensurate'?

When two things are described as 'commensurate,' it means that they correlate or have a mutual relationship in which they are proportional or corresponding to each other in some way. This term is often used in contexts where there is a comparison indicating that the two entities align or match in scale, size, amount, or value.

For example, in a financial context, if an employee's salary is commensurate with their experience, it suggests that their pay is aligned with their level of expertise—implying a degree of equivalence in terms of what is deserved or expected.

The other options—inequality, variation, and opposition—do not accurately represent the concept of being commensurate. Rather, these terms suggest a lack of alignment or compatibility, which directly contrasts with the idea of a mutually corresponding relationship. In essence, the correct interpretation highlights the notion of correlation and proportionality between the two subjects in question.
