Does the word "painly" exist, meaning "causing pain", like "dead" - "deadly"
Eg. "a thick painly truncheon"
Or should I use painful instead?

If "painly" is not a proper word, can I use it still in the quote marks to imitate child's speech?

Thanks

Answer

No it is not a word.
Plainly or painfully which have diffrent meanings. But not painly. It doesn't exist. Therefore I wouldn't use it at all.
