The word "urian" is a rare word that is sometimes spelled with a "y" instead of a "u" (i.e. "yrian"). The phonetic transcription of this word is /juːriən/ which represents the pronunciation in Received Pronunciation (RP) English. The /j/ at the beginning of the word indicates the "y" sound. The /uː/ represents the vowel sound, which is similar to the "oo" sound in "spoon". The /r/ is pronounced with a slight trill in RP English. Finally, the /iən/ represents the suffix "-ian", which is used to form adjectives or nouns from proper names or nouns.
