(1a) "The sentence is wrongly written." x (1b) "The sentence is written wrong/wrongly."

(2a) "The sentence is rightly written." x (2b) "The sentence is written right/rightly."

Could you correct all the sentences and complete the second pair of the sentences, which I am not sure of?

Would you be so kind as to give a clear explanation when these adverbs are used and what are the differences in usage?

Thanks in advance.

All are acceptable. Just as with a few other adverbs, like 'slow', these can take the same form as the adjective when post-modifying, though they are considered casual by some.

Thank you Mister Micawber.

Could you show me a little clearly what posts of the adverbs are considered casual by some people? I mean if you could supply with some exemplary sentences.
The sentence is written wrong.
The sentence is written right.
You are driving too slow.
Yes, I thought so.

I think you are likely to come across these posts of the adverbs in conversation or speech, aren't you? The sentence is written wrong.=> People would tend to use this one instead of wrong-ly in disccusion, wouldn't they?
