Max’s opposite

The crossword question is asking for the opposite of the name Max. In this case, the opposite of Max would be MIN. This could be interpreted in a few different ways, such as looking at the first letters of the names (with ‘M’ being the opposite of ‘N’), or considering the names as representing maximum and minimum values, with Max representing the highest possible value and Min representing the lowest possible value. Regardless of the interpretation, the answer to the crossword question is MIN.
