Torpid is an adjective that means lethargic.

Our word of the day comes from the Latin word torpere (tor PAIR ay) which means ‘to be numb or sluggish.’ Torpid can be used to describe a lethargic person but it can also be used to describe an animal that is dormant or in hibernation.

During most of my torpid youth, I spent all day playing video games and watching TV. I’ve now become a lot less lethargic. I spend a lot less time watching TV.
