This word was invented in 1935 by Everett M. Smith, president of the National Puzzlers' League (N.P.L.), at its annual meeting. The word figured in the headline for an article published by the New York Herald Tribune on February 23, 1935, titled "Puzzlers Open 103d Session Here by Recognizing 45-Letter Word":

Pneumonoultramicroscopicsilicovolcanoconiosis succeeded electrophotomicrographically as the longest word in the English language recognized by the National Puzzlers' League at the opening session of the organization's 103rd semi-annual meeting held yesterday at the Hotel New Yorker. The puzzlers explained that the forty-five-letter word is the name of a special form of pneumoconiosis caused by ultra-microscopic particles of silica volcanic dust...

Subsequently, the word was used in a puzzle book, Bedside Manna, after which time, members of the N.P.L. campaigned to include the word in major dictionaries.

This 45-letter word, referred to as "P45," first appeared in the 1939 supplement to the Merriam-Webster New International Dictionary, Second Edition.

I used to run through the street
But now Covid-19 is running through it
I could call this afreet
But this is a virus, not a demon in Arabian and Muslim mythology

Here and there, you   hear complains of fever, dry cough, and tiredness, that’s vexatious
All we can do now is to kneel down to The Most High to work his miraculous
I have faith he will hear our bloodcurdling screams as we’re frightened by this virus, it’s obnoxious
This virus is nothing but infectious
And it loves people with health complications like Aids on promiscuous

When it comes to killing, this virus is second to nothing
It can’t be compared to Pneumonoultramicroscopicsilicovolcanokoniosis
Og, now you think of electrophotomicrographically?
You being a logophile but this is a virus, not a terminology

This virus doesn’t know the human value
It throws them on deathbed like a coin of low value
This is not a boffola either but a bobsy-die
This virus is comminatory that doesn’t need comess
If this was a person could be a super-star artist with his works in Albertopolis
But this is a virus that is devastating and malicious
Its complications increase with seniority, and that makes it amphibology
It takes on the world in a circuitous thus why I call it anfractuous

Covid-19 has world’s economy in *******
But soon The Highest will have this virus in the shellacking
Until it collapses
It’s about time it teetering
Though the government thinks we’re gullible
This why they told us they have it under control but it is still looming

The medicine is still in its trial stage
And it comes with debilitating side effects
There is a possibility of another wave to come
We have to adhere to doctors’ guidance before it hit us

So let’s isolate
To avoid incubation
And self-quarantine
Before Covid-19 finished our generation
And practice social distance
To save our nation
