The spelling of the name "Gilian" can be a bit confusing, as there are different variations such as "Gillian" and "Jillian". The phonetic transcription of "Gilian" is /ˈdʒɪliən/, with the stress on the first syllable. The use of the letter "G" is a common way to represent the sound /dʒ/ in English, while the use of "i" before the letter "l" represents the short vowel sound /ɪ/. Therefore, the correct pronunciation of "Gilian" is "JIL-yən".
