Idler is a noun that refers to a habitually lazy person.

Our word of the day has its origin in the Old English word idel (EE deel) meaning ‘empty’ or ‘useless.’ It soon evolved into the contemporary English word idle and with it, came the word idler to describe someone inclined to be idle or useless. Here’s an example:

You can’t really be an idler in the real estate business. If you sit around and waste your time when you should be hustling, someone else will take your sales.
