Donald Trump's favorite topic on Twitter is himself.
A little over a year after making his campaign announcement, NBC News analyzed more than 6,000 tweets from Trump, including retweets, to learn about how the presumptive Republican nominee uses the platform.
Trump's most frequently used words
Trump's most commonly used word, excluding filter words like "the" or "and," is "I." Following that is "Thank," which Trump uses about half as often. "#Trump2016" comes in third.
Overall, Trump tends to talk about his main campaign theme ("making America great again"), his opponents and his national media appearances. As the graphics below demonstrate, Trump tends to use different language depending on whether he is talking positively or negatively about these topics.
Words used when tweeting negatively
Trump tends to use the word "bad" when he wants to point out something he feels negatively about. He also tends to use adjectives that underline an opponent's lack of strength or integrity. Honesty and legality are major themes for Trump, and he tends to point out where he sees them lacking in harsh tweets about Ted Cruz, Hillary Clinton, Marco Rubio or Jeb Bush.
Words used when tweeting positively
Trump uses positive language most often when reinforcing his campaign. He emphasizes experiences he finds "amazing," like his campaign rallies or some media appearances or articles. Sean Hannity, Piers Morgan, Gene Simmons and the conservative news site Brietbart make frequent appearances in these tweets, as do the debates and states where he wanted to perform well during the primaries.
