Lol youngling simply means a young one, but I wouldn't want about 5 padawans coming after me lol. Actually there may be a video of that somewhere in the future lol.
Seriously though, good stuff.
According to the book The Jedi Path, the term "youngling" and "Jedi Initiate" are used interchangeably, but are radically different from the term "padawan".
As a Jedi Initiate (or youngling), your training can start as early as two years of age. You live within the confines and relative safety of the Jedi Temple. You learn the basics of what it means to live the life of a Jedi. It isn't until about the time that an Initiate reaches the ages of 12 to 14 that he or she can be chosen to become a Padawan and accompany a Jedi Knight or Jedi Master.
"The life of a Padawan is radically different from that of an Initiate. Your activities as a youngling were shared and structured, but as a Padawan, you will be executing open-ended missions and will be expected to keep up with Jedi wo outmatch you in every step". The Jedi Path, page 50, second paragraph.
These children here would be considered younglings or Jedi Initiates, learning the basics of lightsaber combat from a master in the Jedi Temple. At some point, they will take part in the "apprentice tournament" in which they will fight against each other. Many Jedi Knights and Jedi Masters are present during this tournament and can or will select their one of the initiates to be their padawan learner.
By the way, Master Nonymous, excellent work with these Initiates! My son was watching them and thought it was really neat. Now I have something structured that I can teach him.
The girl in particular seems to be the best out of all of the students. Kudos to all!!
