I was a kid who loved to use big words. At 7 or 8, adults would be really impressed with the way I talked. However, most of my lingo came from just listening to people speak; my parents talking to one another, television, adults in public places conversing.
Well, I heard the word "thoroughly", but hadn't heard the word "thorough", so, for like, five years I thought the word was "thurral".
One Easter when I was about 13, after hours of searching for my prize egg, I had this conversation with my sister:
"But I've been really, really thurral!"
"You've been what?"
"You know, I've searched very thoroughly."
"Oh, you mean you've been thorough?"
"NO, I was thurral!"
She never let me live that one down.
