This is about both the origin and pronunciation of this name. The origin is actually from the English/German Gerard. It is pronounced "jer-RAHD." The "rod" at the end should be pronounced like the word "rod." The difference in spelling from Jared or Jarred in meant to clearly differentiate the sounds. Over time, some English speakers have "mistakenly" used the name as "Jared," despite its very clear difference in phonetics.
