Replace the sod of

RETURF

Think of what you might do to a worn-out lawn or sports field to give it fresh grass coverage. The word starts with "re-" as in doing something again.

"Replace the sod of" is a clever play on words where "sod" refers to grass or turf. The word "replace" hints at the prefix "re-," meaning to do again. Combine "re-" with "turf" (another word for sod), and you get "returf," which literally means to replace the grass. The clue uses a straightforward definition paired with a simple wordplay trick.
