The word "McComas" is spelled with a combination of letters that do not follow the usual English language rules. The phonetic transcription of this word is /məˈkoʊməs/, which indicates that the "Mc" is pronounced as "mək" and the "Co" is pronounced as "koʊ." The irregularity in the spelling comes from the Gaelic language where the "Mc" prefix means "son of." Thus, the word "McComas" comes from the Gaelic name "Mac Thomas," meaning "son of Thomas."
