Root Explanation

Sniffer → The word is formed from "sniff" (of uncertain origin, possibly imitative of the sound made when inhaling) and the suffix "-er" (meaning a person who performs an action). A sniffer is a person or device that performs the action of sniffing, typically to detect or identify something by smell.

Memory Tip

Think of someone who 'sniffs' to detect scents — the '-er' indicates that this person is actively doing the action of sniffing.
