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:
beacon bacon
ceiling sailing
fever favour
displease displays
mystique mistake
need neighed
needier nadir
ouija wager
PE PA
peacemaker pacemaker
people papal
seashells Seychelles
specious spacious
steeple staple
unfeeling unfailing
wheels Wales
The mean density is 6.8%. The 549 pairs make 304 semantic contrasts, a semantic loading of 54%.
