A malapropism (AKA dogberryism or acyrologia) is a phrase or word that can substitute to sound like another word phrase. Just like when you have some misheard song lyrics (These are called mondegreens btw), usually these have funny stories if they come up in real life situations. Here are a few examples of ones I’ve come across:

While on a tour at a winery, the tour guide was showing the different sizes of bottles and what they are called and used for. He pointed to a very large one and I swore he said, “This one is the annihilator.” What he really said was, “This one is the nine liter.”

Mahatma Gandhi walked barefoot everywhere, to the point that his feet
became quite thick and hard. He also was quite a spiritual person.
Even when he was not on a hunger strike, he did not eat much and
became quite thin and frail. Due to this diet, he wound up with very
bad breath. Therefore, he came to be known as a . . .

Super calloused fragile mystic plagued with halitosis.

Do you have any examples of #phrases that sound like other phrases?

I used “Meaningness” in a sentence yesterday, and the other person questioned the existence of that word. I faltered, thought about it, and we came to the conclusion that it was not a word, and that i should have just used “meaning.” Post-conversation thoughts made me think of why I used that word. I swear It’s in songs somewhere, but I can’t find any lyrics (that i know) through a google search. But i felt vindicated that my instincts were right, even though they were also second guessed. Further thoughts on the word though make me try to think of a time when  “meaningness” is necessary and not able to be replaced with “meaning.”   so meaningness is meaningless.
