I'm wondering what it is called when a non-transitive verb is used as a transitive verb. An example would be if someone took the dog outside so it could defecate, and said,
I pooped the dog.
I know the term anthimeria refers to using one part of a speech as another. Wikipedia says that anthimeria...
involves using one part of speech as another part of speech, such as using a noun as if it were a verb: "The little old lady turtled along the road."
but it doesn't say whether the term applies to using a non-transitive verb as a transitive one. Although "poop" is also a noun, it is defined as a verb as well and is being used as a verb, so...
I pooped the dog
seems like it doesn't qualify as "anthimeria" by definition, but it's clearly a related linguistic phenomenon, so I assumed that there must be a term or explanation for this. However, searching online on Google and Wikipedia, I have not been able to find any analysis of that kind of switch.
