Donald Trump has occasionally commented on common English words in ways that suggest he views them as novel, unusual, or newly popularized (often by himself during campaigns), though he has not literally claimed to have “invented” most of them in the sense of creating them from scratch. These remarks are typically off-the-cuff and have been widely mocked or fact-checked as exaggerations. Here are the notable examples based on public statements:

• Groceries: Trump has repeatedly called it an “old-fashioned” but “beautiful” or “very accurate” word, and in some contexts implied he popularized or “started using” it prominently during his campaigns to highlight food price issues. For instance, he has said things like “I started using the word – the groceries” or mused that it describes “a bag with different things in it.” (The word dates back centuries.)
• Affordability: Trump has frequently referred to it as a “new word,” a “Democrat scam,” a “con job,” or a “hoax” invented by opponents to criticize his economic policies. He has said phrases like “They have this new word called affordability” or “The new word is affordability.” (The term has been in common use for decades, especially in economic and policy contexts.)

Other instances where Trump has claimed to coin or invent words/phrases (more directly):

• Equalizing (or “equalize” in context): In 2025, while discussing drug pricing or trade, he said he came up with “a new word… equalizing,” calling it “probably the best word.” (First known use around 1599–early 1800s.)

These are the primary examples tied to recent or notable remarks. Trump has a history of boasting about popularizing terms like “fake news” or “priming the pump,” but those are phrases he claims to have elevated rather than everyday words.

Sigh.
