Sometimes it is difficult to get all the things in books. It is not a piece of cake. U have to go around and search every where. This sort of pair of words are not available in a single book, u need to augment ur vocablary for the sake of attempting pairs of words in a best way. Use GRE books and always try to use right spellings of words.

All d best
Regards
