Root Explanation

**Preamplifier** → It is formed from "pre-" (meaning before) and "amplifier" (from Latin "amplificare", meaning to enlarge or increase). The word "preamplifier" refers to a device that increases the strength of a signal before it is amplified further.

Memory Tip

Think of a device that 'increases' ('amplificare') a signal 'before' ('pre-') it is further amplified — that's what a preamplifier does.
