Question

Which reference source would be BEST to use to find the root word for navigable found in Section 131 of the document?

Answer 1

A. Dictionary

When you look up an entry in a dictionary, you will find a lot of information besides just a word’s definition. In addition to the definition you will find a word’s part of speech (whether it’s a noun, verb, adjective, etc.), pronunciation, language of origin, syllable break up, prefixes (if any), suffixes (if any), and root.

Answer 2

The correct answer should be A. Dictionary

And not just any dictionary, an etymological dictionary that would help you find the root word and how the word came into existence.
