What is the root of word invert?

The root of the word "invert" is the Latin word "invertere", which means "to turn upside down" or "to reverse".

This is a good example of how Latin roots can help us understand the meaning of English words. The prefix "in-" means "into" or "against," while the root "-vert" comes from the Latin verb "vertere," meaning "to turn." So, "invert" literally means "to turn into the opposite position."
