The word "privette" is spelled with a "vi" instead of a "ve" because it is derived from the French word "privé" which means private. In French, the "v" sound is pronounced as "v" while in English it is pronounced as "vi." Therefore, the spelling of "privette" reflects the anglicized pronunciation of the word. In phonetic transcription, "privette" would be written as /prɪvɪt/.
