I'm sure too. But if you're not sure, look up each of the words in a dictionary.
ok thank u for ur help
Yes, you are correct. The word "barren" is not a synonym of fertile. To determine this, you can look up the definitions of each word or use a thesaurus to find synonyms for the word "fertile." By doing so, you will find that "fecund," "productive," and "prolific" are all synonyms of "fertile," meaning they have a similar meaning, while "barren" means the opposite, or infertile.
