This is number 5 in the series of Learn Ancient Egyptian Hieroglyphs. For ease of identification, Sir Alan Gardiner created a classification system for hundreds of the more common hieroglyphs. He listed them into easily identifiable groups and his system has become the standard classification system used by Hieroglyph scholars today. To reiterate he only listed the more common hieroglyphs but we have refined his system and added hundreds of their variations for a total of over 2000 hieroglyphs!
