Well colloquially "pet" itself is a past tense. Depends on the register of the language. And "wrong" is also an adverb. It would help if the educators explain when to use "wrong" vs "wrongly" vs "wrongfully" since all could be adverbs; or you could read enough to figure out the subtle differences.

I had recently looked up “wrong” to check out of curiosity, and DuckDuckGo only said it was an adjective, so I had stopped using it as an adverb. It turns out that the dictionary states it is an adverb, but you need to click to go to an actual dictionary to see that since the definition given by DuckDuckGo is only a partial definition. Thanks for making me double check.

That said, I read dozens of English books per year. I am well past the point of diminishing returns for benefits from more reading in English. Reading more books only increases my reading speed , which I have noticed is now 2 to 4 times faster than others around me.
