Empty words are the words that do not add any meaning to the structure of the sentence. They may be used to add a subjective tone to the sentence but they do not alter the original meaning .
<em>I like to sail when it’s breezy</em>. This is the correct option. The sentence is plain without any emphatic / subjective expression.
These options have empty words:
-I like to sail when it’s <u>very</u> breezy. The underlined word is qualifying <em>breezy</em>.
-I <u>really </u>like to sail when it’s breezy. <em>Really</em> means <em>in fact</em>, it sets the focus on the speaker's opinion.
- I <u>really </u>like to sail when it’s <u>very</u> breezy. Two emphatic or empty words are used.
