Step-by-step explanation:
The two resources that would best help you to clarify understanding of an unfamiliar word are the dictionary and the thesaurus.
A dictionary provides the meaning, pronunciation, and usage of words, while a thesaurus provides synonyms and antonyms for words.
For example, if you encounter the word 'abundance' and are unsure of its meaning, you can look it up in a dictionary to find that it means a large quantity or plentifulness. If you want to find other words with a similar meaning, you can consult a thesaurus which will provide you with synonyms like 'plenty', 'wealth', or 'profusion'.
