"A damaged area of the skin where it has been rubbed against something hard and rough."
The antecedent of the where clause which "where" referring to is the "damaged area" and "it" referring to "the skin"
Am I right about that?
This sentence comes from a definition of the word "abrasion" in a dictionary. I do know what it means in a vague sense, just for reading, the job is done. what is not clear, and makes me wonder, is "where" and "it" refers to which word or phrase and if I can know this, I think I can master it completely.
This question might seem silly by native speaker, but it does worth answering for the reason to understand and generate sentence for a second language learner.
and @jacob, thanks for your explanation, it's very kind of you to spend you time to help silly learner like me. The transfer from "where it" to "that" makes the meaning clear. Can you show what both "where" and "it" refers to if you have time. Thank you.
