English is constantly changing. Some other languages, like Latin and Chinese, are tied to state regulations, but English has always been free to change and adapt, losing and gaining meanings as it goes. In fact, it's one of the most change-prone languages in human history.

This ability to take on new meanings and large amounts of completely different languages is how English survived multiple attempted cultural genocides and eventually rose to global dominance.

Why are there so many Latinate roots in English, if English is derived from Pict, Celt, and Germanic/Nordic mingling? Because French is a Romance language and ruled over England for two full centuries. But instead of being smothered, English absorbed the oppressor language. This is why so many of our words to do with courtly, religious, and legal matters are French in origin, like chivalry and cathedral.

Words in English are just going to constantly change to reflect the cultures using the language at the time. Any attempt to ground any English word in one single definition is doomed to failure, so you really shouldn't try.
