What You'll Learn
'Zzz' as an onomatopoeic representation of snoring
The use of "Zzz" to represent sleep and snoring can be traced back to the late 19th and early 20th centuries, when comic strips and comic books became popular. Artists would indicate that a character was asleep by portraying them as snoring, as it was a dynamic way to visually convey sleep.
The letter "Z" was used to represent the sound of snoring, an onomatopoeic device. Onomatopoeia is a figure of speech in which a word is formed by imitating the sound it describes, like "boom", "crash", or "bang". In the case of "Zzz", the sound of snoring was represented by the "zzz" sound, which caught on and became a standard way to indicate sleep and snoring in comics and cartoons.
The first use of "Zzz" to indicate snoring can be traced back to 1903 in the comic "Katzenjammer Kids" by Rudolph Dirks. Dirks often used variations of "Zzz" to indicate snoring, and other comics soon followed suit, with "The Fineheimer Twins", "Krazy Kat", and "Boy's Life" all using "Zzz" throughout the 1910s. By 1918, its place in the lexicon was solidified, as it earned its own entry in the American Dialect Society's notes.
The use of "Zzz" to indicate sleep and snoring then spread beyond comics and into popular idioms like "catching some Zs", which means to sleep. The letter "Z" became permanently linked to sleep, and its use spread internationally, although many languages have their own unique onomatopoeic representations of snoring.

The history of 'zzz' in comics and cartoons
The use of 'zzz' in comics and cartoons to indicate sleep or snoring has a long history. The first recorded use of 'zzz' to indicate sleep was in 1903 in the comic "Katzenjammer Kids", created by Rudolph Dirks. In the comic, the snoring Captain sleeps peacefully in his hammock, emitting z's, while the mischievous Katzenjammer kids cut his beard with a mower and then cut the hammock's strings. Dirks didn't exclusively use 'zzz' in his portrayals of snoring, but he often relied on variations of it.
Following "Katzenjammer Kids", other comics such as "The Fineheimer Twins", "Krazy Kat", and the humour section of "Boy's Life", the Boy Scout Magazine, all followed suit by using z's throughout the 1910s. By 1918, its place in the lexicon was solidified, earning its own entry in the American Dialect Society's notes.
The reason for the letter 'z' and its association with sleep can be traced back to the idea that the shape of the letter 'z' and the motion of sawing wood with a hand saw are similar. The sound of sawing wood, "zzzzz", became associated with the sound of snoring, and over time, with sleep in general. This theory is supported by the fact that in the past, the description given to the sound of snoring was "sawing wood", often accompanied by an image of sawing or a hand motion in the "z" formation.
The use of 'zzz' in comics and cartoons became a convention, especially in American comics, to indicate that a character is sleeping. This can be seen in Charles Schulz's "Peanuts" comic strips and Jim Davis's "Garfield". In one strip, Garfield is unable to sleep because his 'zzz' bubble is pointing in the wrong direction. When he grabs the bubble's tail to make it point at himself, he falls asleep.
The popularization of 'zzz' in comics and cartoons has also led to the phrase "catch some Zs" and the verb "zonk (out)" which emerged in the 1940s to convey suddenly falling into a deep sleep.

The meaning of 'catching some z's'
The phrase "catching some Zs" refers to taking a nap or going to sleep. The expression alludes to the buzzing sound of snoring. The use of the letter "Z" in this context can be traced back to the early 1900s and the comic strip "Katzenjammer Kids", created by Rudolph Dirks, in which the snoring Captain emits Zs while sleeping in his hammock. The use of "Z" to represent snoring was then picked up by other comics in the 1910s, and by 1918, it had earned its own entry in the American Dialect Society's notes.
The phrase "catching some Zs" is just one of the results of the popularization of "ZZZ" to represent sleep. In the 1940s, the verb "zonk (out)" emerged to convey suddenly falling into a deep sleep. While "catching some Zs" is commonly used in the US, in countries like the UK, Canada, and Australia, a tired person might say they need to catch some "zeds," and a nap may be called a "zizz."
The use of "Z" to represent sleep and snoring is not universal, however. In German, the sound of snoring is represented by "chrr," while in French and Spanish, speakers use variations of "roon" or "rrr." In Japanese, the characters sound like "guu-guu," and in Mandarin, it's akin to "hu-lu." Nonetheless, "ZZZ" has made its mark internationally as a symbol for sleep.
There are also a number of apps that use "ZZZ" in their names, including one that helps users fall asleep faster and another that is a sleep tracker widget. These apps offer features such as sleep sounds, sleep tracking, and insights into sleep schedules.
