Morphology
invariance = invariant (transparent) = invari + ance
The noun 'invariance' is transparently formed from the adjective 'invariant' with the suffix '-ance', meaning the state or quality of being invariant.
Etymology
Invariance comes from the prefix in- meaning 'not' and the root var- (seen in the common word vary) meaning 'change'. So, invariance means 'not changing', which is why scientists use it for things that stay the same even when other things change.
