Trump has an unusual habit of capitalizing random words in his tweets — writing experts take their best guesses why

  • President Donald Trump has an unusual writing style that has caught the attention of linguists and writing experts.

  • The president has been criticized for his unconventional way of capitalizing words that aren't proper nouns, including "border," "military," and "country."

  • There are some interesting theories as to why Trump capitalizes words the way he does.

President Donald Trump's tweets have captivated the public for years now. He's used them to fire people, make policy announcements, vent his frustrations, and insult his enemies.

While much of the public's focus has been on the content of Trump's tweets, there's one cosmetic aspect that has grabbed the attention of linguists and writers: his unconventional capitalization of words.

For as long as Trump has been tweeting, he's demonstrated a bizarre habit of capitalizing words that typically don't get capitalized. He routinely capitalizes words like border, country, safety, security, and military, and several other words.

Take a look at some examples just from this past month:

On Wednesday: "There is a Revolution going on in California. Soooo many Sanctuary areas want OUT of this ridiculous, crime infested & breeding concept. Jerry Brown is trying to back out of the National Guard at the Border, but the people of the State are not happy. Want Security & Safety NOW!"

On Tuesday: "States and Cities throughout our Country are being cheated and treated so badly by online retailers."

On Monday: "I never asked Comey for Personal Loyalty."

The public has started to take notice of the practice, too. Wander into the reply section of one of Trump's offending tweets and you'll find scores of readers criticizing the president's writing style.

Theories abound for why Trump capitalizes words the way he does. One belief, as suggested by CNN's Chris Cillizza, is that it's his way of drawing attention to the words in question. Twitter doesn't allow users to type in bold or italics, so perhaps Trump has found a creative solution.

Alternatively, it could be possible that Trump simply doesn't know the conventions of English capitalization, which generally dictate that only proper nouns and the first word of a sentence get capitalized.

"He's turning things that are not proper nouns into proper nouns, which does give them an importance they don't really have," writing coach Mary Cullen told Business Insider. "Grammatically, it doesn't make any sense."

Intentional or not, Trump's capitalization habit does fall in line with his knack for branding. In many cases, the words he chooses to capitalize — think "Fake News Media" and "Witch Hunt" — reflect his personal spin on the issues that are most important to him.

"Many of them look like phrases that you could put on a hat or a political button or a bumper sticker," Roy Peter Clark, a writing teacher with the Poynter Institute, told Business Insider.

Cullen agreed: "It's something he can easily make a buzzword out of," she said." "He's sort of making it a Thing, with a capital T."

Trump isn't alone in his unique writing style. Believe it or not, Trump's style of uppercasing seems to be a trademark of speech used by Tea Party members, as writer Jon Lackman observed in a Slate article from 2010. Exactly why is hard to tell, but Lackman noted the style hearkens back to colonial America — you may recall the Declaration of Independence mentions "Life, Liberty and the pursuit of Happiness," among other capitalized words that appear to defy convention by modern standards.

Regardless of Trump's intent, the degree to which his writing style angers people likely correlates to where they fall on the political spectrum — much like his affinity for assigning provocative nicknames and his tendency to commit spelling errors. As Clark put it, such moves are unlikely to move the needle for someone who supports the president.

"It appears that all readers seem to bring partisan preferences to the act of reading," Clark said. "So I would guess that these practices will continue to enrage his opponents and encourage his faithful core of true believers."
