Is a root word at the front of word?

That's not quite right! A root word is the core of a word, and it can be found within the word, not necessarily at the front.

Here's an example:

* "Unbelievable"

* Root word: "believe"

* Prefix: "un"

The root word "believe" is in the middle of the word, and the prefix "un" modifies its meaning.

So, the root word is the foundation of the word, and it can be located anywhere within the word's structure.
