The root word is the part of the word that helps define the meaning. It can be at the beginning of the word, middle, or end. These are called the prefixes, bases, and suffixes.
Since "products" and "produce" have the same root word of "pro" and have similar meanings-things that are made, making things- they have the same root word. However, C. prompt also has the same root word of pro but it doesn't have a similar meaning.
