Match items in two ranked lists

I want to sort and match items in a ranked list without losing their ranking. I have attached a picture of the first 20 rows of data.

Column A is the frequency ranking for a list of words in Column C
Column E is the frequency ranking for a list of words in Column D

I want to learn how to sort columns C and D (the words) so I can see identical words matched up next to each other, keeping the correct ranking in the column next to each word. e.g., I want Excel to show me by a sort which items in one list have an identical partner in the other list.
