Here's why:
* Conjunctions connect words, phrases, or clauses. They show relationships like addition, contrast, cause and effect, etc. Examples include "and," "but," "because," "so," "or."
* "Yikes" is an interjection. Interjections express strong emotions or sudden feelings. They are often stand-alone words.
Let's illustrate:
* Conjunction: "I went to the store, and I bought some milk." ("and" connects the two phrases)
* Interjection: "Yikes! That spider is huge!" ("Yikes" expresses surprise)
