The New York Times writers were warned not to use the word "tweet," Sky News reported Friday.
As the use of Twitter continues to grow, words like "tweet" and "twittering" have increasingly cropped into everyday use.
But editor of The New York Times, Phil Corbett, said it was unacceptable.
He sent a memo to writers Wednesday telling them not to use the T-word, which he called "inherently silly."
"Some social-media fans may disagree, but outside of ornithological contexts, 'tweet' has not yet achieved the status of standard English," Corbett said in the memo, obtained by website The Awl. "And standard English is what we should use in news articles."
"Except for special effect, we try to avoid colloquialisms, neologisms and jargon. And 'tweet' — as a noun or a verb, referring to messages on Twitter — is all three."
The word tweet appeared 18 times in article in The New York Times in the past month, which prompted Corbett to put his foot down.
