For instance, the term “goodbye” is an eroded version of the longer phrase “God be with you”.
But at the same time, there is an innate human need to simplify. And so, while they grow, languages also shrink via contraction or erosion. For instance, the term “goodbye” is an eroded version of the longer phrase “God be with you”. And today, it’s actually even more common to say “bye” than “goodbye”. Somehow “God be with you” has morphed into “bye”.
