The word "sniffing" is spelled with two "f's" because the first syllable of the word is stressed and ends in the phoneme /f/. In IPA transcription, this sound is represented as /f/. The second syllable of "sniffing" ends in the /ɪ/ vowel sound, which is typically spelled using a single "f" in other words. However, since the stress and the /f/ sound occur in the first syllable, we use two "f's" to maintain consistency in the spelling of this word.
Sniffing is a term commonly used to describe the act of inhaling or breathing in a substance through the nose, often to detect or identify different scents and odors. It is a natural and instinctive behavior in humans and animals that allows them to perceive various smells in their environment.
In a broader sense, sniffing can also refer to the intentional inhalation of substances for recreational purposes. This practice involves inhaling chemical vapors or volatile solvents to achieve a desired high or altered mental state. Common substances used for this purpose include solvents like glue, paint thinner, gasoline, or aerosol sprays, as well as certain prescription medications or illegal drugs.
When used in the context of computer networks and technology, sniffing refers to the process of capturing and analyzing network traffic to gather information or intercept data packets. Network sniffers (also known as packet sniffers or protocol analyzers) are software or hardware tools used by administrators or hackers to monitor, troubleshoot, or exploit network activity. They allow users to analyze packets of data passing through a network interface, examining their contents, source, destination addresses, and protocols. Network sniffing can be either a legitimate method for network troubleshooting and diagnostics or an illicit activity used for unauthorized access, data theft, or network attacks.

The word "sniffing" is derived from the Middle English word "sniffen", which can be traced back to the Old English word "snyffan". This Old English term originally meant "to smell, sense, or be inquisitive". Over time, it evolved to specifically refer to the act of drawing air in through the nose audibly or forcefully to perceive odors. The word "sniff" as a noun also emerged during Middle English to describe the sound made when sniffing, and eventually, the term "sniffing" was derived from it to denote the action itself.
