What's considered more painful of the following three words? I saw on the dictionary that all of the following three words: ache, painful and sore have the same meaning and it's not clear to me if they're just synonyms or they have some subtle differences. (I know that "ache", unlike sore and painful, is a noun rather than an adjective, but still the difference between I'd like to know if there is a difference in the meaning.)
👉* She's got a sore back. Vs. She's got a backache Vs. She's got a painful back.
👉* All the dust has made my eyes sore. Vs. All the dust has made my eyes painful. Vs. All the dust cause to my eyes to (be) ache.
