As I have found on my simple research, context clues are useful to learn meaning of dictionary words. For academic purpose, I need corpora of example sentences for dictionary words that contain such context clues as definition, contrast, example, restatement etc. It would be ok if I find 100-200 example sentences in each context clue category. Could anyone point me towards such resources?
Update:
If you are new to the concept of context clues, please refer to this site. For the type of sentences I am looking for, please refer to this site.
Thanks in advance.
