Adjective
Definition: present in all places at all times
I encountered this word while reading The Brooklyn Bridge.
Best way to understand this word would be like in this sentence, “The problem is omnipresent and unavoidable.” Now I understand what the word means and how it was used in the paragraph about the Brooklyn Bridge.

I’m glad you understand how the word is being used in that sentence–now you need to explain it so your readers can understand it, too.
