The correct spelling of the word "Vigidis" is often disputed. It is believed to be of Latin origin and is used to describe a plant commonly known as "mugwort." The word is typically pronounced as "vij-i-diss," with the "g" being silent. The consonant combination "gi" is often pronounced as a "j" sound in Latin and Italian words, which explains why this pronunciation is commonly used. However, there are some who pronounce it as "vig-i-diss" with a hard "g" sound.
