The word "Antigalastic" is not commonly known, and it might even be unheard of by most people. However, its spelling can be explained through the use of the International Phonetic Alphabet (IPA). The word is often spelled phonetically as /æntiɡəˈlæstɪk/. This means that there is an "a" sound at the beginning, followed by a hard "g" sound, then another "a" sound, and finally, an "i" sound. The word ends with a combination of "l," "a," "s," "t," and "i" sounds, which are pronounced as they would appear in the alphabet.
