The spelling of the phrase "man breeding" is straightforward when using the International Phonetic Alphabet (IPA). The first word, "man," is spelled as /mæn/ in the IPA, with a short "a" sound (as in "cat"). The second word, "breeding," is spelled as /ˈbriːdɪŋ/. It starts with a stressed long "e" sound (as in "bee"), followed by a "d" sound and ending with the "ing" suffix pronounced as "in". Therefore, the correct spelling of the phrase "man breeding" in IPA is /mæn ˈbriːdɪŋ/.
