What does “doorzagen” mean in Dutch?

Doorzagen literally means to saw through something completely — door (through) + zagen (to saw). In everyday Dutch, though, the same verb means to keep harping on a topic, to drone on without stopping. The two senses sit at opposite ends of the register: one belongs to a workshop, the other to an exasperated dinner table. Knowing both meanings stops a very common colloquial verb from sounding like a power tool.

In this clip, a climate scientist explains how slicing open an oyster shell — doorzagen — reveals annual growth layers, much like tree rings. The precision of the gesture makes the figurative meaning all the funnier: zagen (to saw) is also Dutch slang for snoring, and afgezaagd (“sawed off”) means stale or worn-out. So the verb family runs from workshop to bedroom to the office colleague who just won’t let a topic go.
