Although this is a contrast between a vowel and a diphthong, there is potential for confusion, especially for those speakers whose language uses a tense /e/ vowel and no front closing diphthong.
I have left in the two pronunciations of re, although I doubt if they count as a minimal pair since they have the same meaning. The pair redid and raided differ in stress as well as vowel quality, but might still be a problem for learners.
The only mildly taboo word pairs are pee/pay and wee/way.
There are a good many interesting pairs which differ widely in part of speech and/or meaning. These include:
The mean density is 6.8%. The 549 pairs make 304 semantic contrasts, a semantic loading of 54%.
