The spelling of the word "cu inmin" is based on the Irish language. In IPA phonetic transcription, it would be written as /kuː ɪnʲmʲɪn/. The first part, "cu," is pronounced with a long "oo" sound, while the second part, "inmin," is pronounced with a short "i" sound followed by a nasalized "n" and a short "i" sound. The word means "little worm," and is believed to have originated in Irish folklore.
