Prefixes: OVER, UNDER
Prefixes: OVER, UNDER

This is Ronald.
Ronald is going for a run.
If I call out to Ronald, "Hey, don't overdo it!" He'll take it easy and not run too much.
If I call out to Ronald, "Hey, don't underdo it!" He'll keep running until he's about to collapse.
Why? Because Ronald knows the meanings of the prefixes over- and under-.
A prefix is a word or group of letters that is placed at the beginning of a word. It helps clue you in to the meaning of the word.
The prefix over- means "more than" or "too much."
The prefix under- means "too little" or "not enough."
So if I tell Ronald not to overdo it, I'm telling him not to do too much and if I tell Ronald not to underdo (a word I just made up) it, I'm telling him not to do too little.
