plods

Plods is the third-person singular of the verb plod, which means to walk heavily and slowly, often with effort or weariness.

The word suggests trudging along without enthusiasm or energy: She plods through the snow to get to work.

By extension, plod describes any slow, laborious progress through a task: He plods through the paperwork each evening.

A plod can also be British slang for a police officer, from the character PC Plod in children's books.
