"Isthmus gyrifornicati" is a challenging word to spell due to its unusual combination of letters, sounds, and syllables. The correct pronunciation of this term, as per the International Phonetic Alphabet (IPA), is /ˈɪs.məs dʒaɪ.rɪ.fɔː(r).nɪˈkeɪ.ti/. This word is derived from the Latin "isthmus" meaning "narrow strip of land" and "gyracuse" meaning "a winding path." "Fornicati" refers to "sexually immoral behavior." The word "gyrifornicati" is a neologism coined in 1968 to describe the dance movements inspired by the sexual revolution of the 1960s.
