ZZZ is an abbreviation of "Sleeping, Bored, Tired". These days, the ongoing trend of communicating through social media with the minimum of words possible has given the use of this word -an impetus. We tend to write a few words to express our emotions and zzz is widely used to refer that someone is sleeping.
Illustrators, animators, and comic writers have widely used this word to represent that someone is sleeping in slumber. No matter where this word is used, whether in comics, cartoons, or animation, it is quite prevalent. The origin and history of this word are vague but interesting. Now let’s first look into the proper meaning of this word.
Zzz is the onomatopoeic representation of a snoring sound. Now the question arises what does it mean by onomatopoeia? Onomatopoeia is the use of words whose sound refers to the sense or in layman's terms we can say that the naming of a thing by a vocal imitation of the sound attached to it. For example, buzz (sound of bees), hiss(sound of snakes), etc.
Zzz is a short word that does not stand for any meaning rather it refers to the sleeping state.
Every word found its way into the dictionary when it is popularised by some great poet or writer, or sometimes by the people i.e. when the word is being used by common people and gets acceptance.
The word Zzz was first used in some Boy’s Life Magazine around 1919, later it was used in many different comic books and it gained popularity with comics and cartoons in the 21st century.
This word is generally used for informal conversation. There is no strict rule to write the first term in capital or anything like that as all these three words convey the same sense- zzz, Zzz, or ZZZ.
We rarely use this word in oral confabulations because it's awkward in that case, so we mostly use it in writing.
Examples:
Here we will understand the examples as a moiety of conversations between two people.
Here Sneha and Rohit are chatting on whats app
Sneha: Hey what’s up !!
Rohit: talk to you later, zzz….
Adarsh and Diwakar are chatting on telegram
Adarsh: Why don’t you catch some Zzz until I return?
Diwakar: Yeah, good idea! Good night.
I found loud noises in the middle of the night from my adjacent room in the hostel. I guess that’s Rohit ‘ZZZ’ing.
Since Zzz is used as a part of informal conversation, it can be used in any form- there is no hard and fast rule to write it in any way, so all three ways are correct.
Figures of speech refer to words or phrases that have different meanings from their literal interpretation. Example: Onomatopoeia, simile, metaphor, pun, etc.
Figures of speech are rhetorical terms that convey different meanings of words than their literal interpretation. For example, similes, metaphors, oxymorons, etc.
Parts of speech refer to different groups in which the English words can be categorized. For example Nouns, Pronouns, verbs, adverbs, etc.
Informal and formal conversations are two different ways of conveying our ideas. The former is fast and aims to meet personal needs and interests while the latter is to fulfill organizational objectives.
So using Zzz for formal conversation would be awkward and it will decrease the gravity of formal communication.
Hence it is recommended to use it for informal communication like with a friend, relatives, etc.
Firstly, we should understand that every word found its way into the dictionary when it is popularised by some great poets or writers, or sometimes by the people i.e. when the word is being used by common people and gets acceptance.
The word zzz found its way into the dictionary because it was widely used by people around the year 2006 - 2008 to convey the idea that someone is sleeping in slumber.
So it is one of those words that get added to the dictionary of English because it was popularised by people.
