Technically, you are correct. But in reverse. For example, you say "I understand" when you want to mean that you are equal in knowledge or when you agree with a statement, thus you are on the same level. But "understand" means that you are under that level. Or "OK" - what even is that. Well, K is a god in Maya mythology https://en.wikipedia.org/wiki/K%CA%BCawiil . Some say "terrific" and mean good, but the root of the word is terror. Well, you get it... :D
