Morphology
parity = par (opaque) = par + ity
Although the form suggests a state of equality, the computing meaning involving an error-detection bit is a specialized technical extension that is not predictable from the parts alone.
Etymology
Parity in computing is a simple error check that adds one extra bit so the total number of 1s is always even or always odd. The word comes from Latin par 'equal', so the check is about making the count 'match' to spot mistakes.
