IPA: /ˈtrʌdʒər/
KK: /ˈtrʌdʒər/
A person who walks slowly and with heavy steps, often because they are tired or burdened.
After a long day at work, he was just a trudger making his way home.
The word 'trudger' is derived from 'trudge' (from Middle English 'truggen', meaning to walk heavily or laboriously) and '-er' (meaning a person who). A trudger is a person who walks heavily or with effort, often implying a sense of labor or fatigue.
Think of someone who is walking heavily or laboriously — that's what a trudger does, and the '-er' just means it's a person doing that action.
