Spending some time in the dictionary is one of the easiest ways to learn something new, and it's super easy/accessible! Here's a word I learned today:
Cyclopean. Cyclopean is a great word to use in everyday conversation, and it's easy to remember because you can just think of Cyclops, and then think of how huge Cyclops is in real life. I'm pretty sure Cyclops is real, right?
Definition: Grand, vast, etc.
Earliest known use: 1582
Use it in a sentence: Those cyclopean creatures at the corn maze were nicer than they seemed.
