iOS autocorrects words when hitting send in Messages

Autocorrect has started “correcting” words after I hit send when in Messages. A lot of the time it’s a word the system doesn’t recognize or in a context that makes autocorrect think I mean something else…but I want it to be spelled that way and I put it there on purpose. It will attempt to “correct” the word at first and I will correct the autocorrect so that it doesn’t change the word. Then, when I hit send, it will go back and correct the word again anyway but I can’t fix it unless I catch it after it is delivered and can edit the message. I can’t edit it on sms so it just hijacks my message and sends out the wrong words.

How can stop this behavior?

Is this something I can fix without disabling all of autocorrect? Autocorrect didn’t work like this until this last update when it seemingly started trying to correct based on context.

(Also, I don’t want links to how autocorrect works. I don’t need the generic replies with “answers” that don’t address the specific question. Don’t point me to an Apple “how-to” link. I can use the search bar. These answers won’t be there.)
