Most of the time when Tate mixes up his words it's not deliberate. But it's usually somewhat logical.
Like when Kerry dug into the stash I have for making s'mores because he wanted chocolate. Tate asked him where the Hershey bars came from, but, "Dad wasn't very tellative, Mom."
Or noticing some chickens that stay in a neighbor's yard, though they're not fenced, he said, "Those are very allegiant chickens."
But other times he knows he's making a play on words.
We were talking about the Gold Rush of 1849. Few of the miners actually got rich. Many of the ones who did find gold tended to squander it on the weekends "in town". Blank stares.
Hmmmm. I was trying to describe what I meant by "wild living" with age-appropriate information, (in other words, I preferred to avoid discussing prostitution with my 8 year-old), when Tate summed it up like this:
"They bamboozed their money away."
