in the epic movie series star wars jedi apprentice grew 1 sing braid of hair to symbolize their rank as an padawan. once a padawan's training was complete his master or a member of the jedi council would chop it off with their lightsaber symbolizing the completion of his training.
A Jedi student. They are past the first part of their Jedi training and are now apprentices to other Jedi masters. They have exceptional skills, to become powerful and great. So Padawans are also called 'My apprentice' by their masters. Or 'My Padawan'
Padawans have small plaits in their hair. This is a good way to spot them. Very cute.
Obi-Wan Kenobi: What took you so long?
Anakin: Well, you know, Master, I couldn't find a speeder that I really liked...
Anakin: ...with an open cockpit and the right speed capabilities.
Obi-Wan: If you spent as much time practicing your saber techniques as you did your wit, you'd rival Master Yoda as a swordsman.
