https://en.wikipedia.org/wiki/Semantic_change:

”Semantic change (also semantic shift, semantic progression, semantic development, or semantic drift) is the evolution of word usage—usually to the point that the modern meaning is radically different from the original usage.”

⇒ you can’t argue Google’s definition is worse because it declares the original meaning to be informal and subsidiary to its corrupted definition. It may just be more up to date (in this case, I think it is)
