The word "Quellio" is spelled with a "Qu" at the beginning, rather than a regular "K" because it is derived from Italian, where "qu" is used for this sound. The first syllable has a stressed "e" sound, represented in the phonetic transcription as /ɛ/. After the stressed syllable, there is a double "l", which indicates that the "l" sound is pronounced twice in quick succession. The final syllable has a neutral vowel sound represented as /i/, similar to the sound in the word "me".
