There are many spellings for /i/ in this list, typically <ee>, <ea> and <eCe>. The vowel /ɔ/ is most often spelled <or>, but also <aw> as in saw, <au> as in author, <al> as in talk, <a> after <w> as in war or walk, <wo> in sword and occasionally <our> as in source, and in one word <oa>, broad. Since /ɔ/ would have a closing -r glide in many words for speakers of a rhotic accent, many of these pairs would not be minimal in, say, the USA.
Vowels /i/ and /ɔ/ would hardly ever be confused in speech, being about as far apart in articulatory setting as possible.
Note the special case of key/corps and keys/corps, quay/corps and quays/corps. Corps counts as a homograph since the anglicised plural is not shown in the spelling.
Note also the pairs arising from a linking -r in compounds or inflected forms: overeat/overwrought, and keyring/coring.
Interesting pairs include:
appealing appalling
cheeky chalky
teacher torture
wield walled
