I think the English word "better" is lacking.  It can mean two entirely different things, based on context.  When you're injured/sick, you can "get better," which means either (a) you're partially healed or (b) you're fully healed.  Those aren't the same thing, but the same word is used in both instances.  If you're bad at school/sports but you "got better," it can mean either (a) you're somewhat less bad than you were, or (b) you're now the best.  It seems like whenever the word "better" is used to describe progress, it requires either an adverb to qualify it (somewhat better, almost better, completely better), or a comparative descriptor to quantify it (better than before, better than you). #language
