Work monotonously refers to a job that requires repetitive and tedious tasks. The term can be broken down into two crossword solutions: DRUDGE (6 letters) and PLOD (4 letters). DRUDGE is defined as a person who does hard, menial, or dull work, while PLOD is defined as to work slowly and steadily, especially at a tedious or laborious task. Therefore, work monotonously can be described as performing hard, dull, and laborious tasks in a slow and steady manner.
