The quality or state of being commutable; the degree to which something can be exchanged, substituted, or mathematically commuted.
From commutable + -ity suffix (creating nouns from adjectives). Built on commute (Latin commutare, 'to exchange') + -able + -ity.
In mathematics, 'commutability' describes whether operations can be performed in different orders with the same result—multiplication commutes (3×5=5×3) but subtraction doesn't, a property crucial to understanding how physical laws work.
