IPA: /ˈdrʌdʒər/
KK: /drʌdʒər/
A person who does hard, menial, or tedious work.
He felt like a drudger, working long hours with little reward.
Drudger originates from the Middle English 'drudgere', which is derived from 'drudge' (meaning a person who does hard, menial work). The term 'drudge' itself comes from the Old English 'drygan', meaning to toil or work hard. Thus, a drudger is someone who engages in hard, tedious labor.
Think of someone who is 'toiling' or 'working hard' — that's what a drudger does, as it relates to the Old English meaning of hard work.
