“what is the purpose of a veil”

I literally just found this on google but it helps lol
A veil is an article of clothing or hanging cloth that is intended to cover some part of the head or face, or an object of some significance. Veiling has a long history in European, Asian, and African societies. The practice has been prominent in different forms in Judaism, Christianity, and Islam.
Hope that helps :)
Answer: A veil will hide her face to ensure the groom won’t see his soon to be betrothed until the ceremony. The veil came to symbolize modesty and obedience.
