The 3 Types of Hiroglyphs

There are 3 types of hiroglyphs logograms, phonograms, and determinatives. Logograms write out morphemes, which I'm not really sure what they are. Phonograms represnt one or more sounds. Determinatives donate neither morpheme or sound, but help with the meanings of the signs that procive them. Pretty complocated if you ask me that's for sure.
