Noctivigant is a noun that refers to someone who wanders around at night. It is also an adjective that means ‘wandering in the night.’

The latin prefix N-O-C-T means ‘night,’ while V-A-G-U-S means ‘wandering.’ Here’s an example of our word of the day in use as a noun. 

I didn’t know Cheryl was a noctivigant at first. I’d wake up in the middle of the night and wonder where she’d gone to. Turns out she was just another nighttime creature who craved those late-night meanderings.
