Sigils are merely "signs" or more simply symbols. That's it!
Personal sigils, or those of specific powers/beings/spirits are like signatures that can be used to call forth that specific energy/presence. Sigil in this case is used interchangeably with the word "seal" such as the infamous "Keys of Solomon".
WhiteRav3n is correct. In one way sigils are symbols for names. However, sigils are also a big part of chaos magick. They can be used as spells on there own. I would suggest you do a search on chaos/sigils
