The spelling of "brought feet" can be explained using IPA phonetic transcription. "Brought" is pronounced as /brɔːt/ with the "ou" sound representing a diphthong of /ɔː/ and /ʌ/. "Feet" is pronounced as /fiːt/ with the "ee" sound represented by the long vowel /iː/. When combining the two words, the "t" sound from "brought" flows smoothly into the "f" sound of "feet." Therefore, the correct spelling is "brought feet" and not "brought feat" as some may mistakenly write.
