Devoid (adjective)- being without a usual, typical, or expected attribute or accompaniment.
“Imagine a world suddenly devoid of doors.”

When I first came across the word devoid it looked weird. I did not use context clues. When I looked up the word on www.merriam-webster.com. I was still confused of its meaning, so I used Microsoft Word synonyms and it gave the word empty. Therefore, the writer was saying to imagine the world without doors.
