解説 Definition
探知器とは、特定の物質やガスを検出し、その存在や位置を特定するための装置です。爆発物検査や薬物検査などに使用される科学的な検出器を意味します。
A sniffer is something or someone that detects, examines, or searches for something by finding signs of it. In technology, it often means a program or device that monitors network data. In general use, it can also refer to an animal, person, or tool used to find smells, drugs, leaks, or other hidden things.
覚え方のコツ Memory Tip
sniff(くんくん嗅ぐ)が分かれば、sniffer は「嗅ぎつけるもの・人」。-er は teacher, reader と同じく「する人/道具」の形。dog sniffer のような生き物にも、packet sniffer のような機器やソフトにも使える。detector が広い意味の「検出器」なのに対し、sniffer は「鼻を利かせて特定物を探る」感じが強い。sniff out(嗅ぎつける)まで一緒に覚えると定着しやすい。
Build it from `sniff` + `-er`: a `sniffer` is something that "sniffs out" what is hard to notice. That makes it easy to remember in phrases like `gas sniffer` or `packet sniffer.` Unlike the broader word `detector`, `sniffer` gives the image of searching for hidden traces.

sniffer の語源・成り立ち Etymology
sniffer は sniff に行為者を表す語尾 -er が付いた語で、「くんくん嗅ぐもの・人」がそのまま形になっています。sniff 自体は鼻をすする音をまねた擬音語系で、sniffle や snivel と近く、機械のスニッファーも「匂いを嗅ぎつける鼻」の比喩だと分かります。
"Sniffer" is made from "sniff" and the suffix "-er," meaning a person or thing that does an action. "Sniff" is probably imitative, based on the sound of breathing in through the nose. Because of that, "sniffer" first meant something that sniffs and later was also used metaphorically for devices that detect things. Related words include "sniffle" and "snivel."
