Skookum is an adjective that means strong, brave or impressive. 

Our word of the day has its origin in the language of the indigenous people of the Pacific Northwest. It’s been used since the late 19th century. Here’s an example of skookum in use:

I found our boss particularly skookum last Thursday when he stood up to his supervisor in defense of his parking spot. He might have impressed me as even braver if he’d defended all of our parking spaces, but I guess you can’t have everything.
