Root Explanation

Seismograph → It is formed from "seismo-" (from Greek "seismos", meaning earthquake) and "-graph" (from Greek "grapho", meaning to write). The word "seismograph" refers to a device that writes or records the movements of the earth during an earthquake.

Memory Tip

Think of 'earthquake' ('seismo-') being 'written down' ('-graph') — that's what a seismograph does.
