meaning of 傳 in 傳不習乎? In Analects, chapter 4,
「吾日三省吾身
為人謀而不忠乎？
與朋友交而不信乎？
傳不習乎？」

I would translate it: Master Ceng said: everyday I check three things in myself:
do I plan my behavior without loyalty? do I make friends without confidence/trust (or deserving confidence - sincerity)? do I propagate (disseminate) the Practice.

James Legge (who is extremely competent in it) translates the last lines differently: whether I may have not mastered and practiced the instructions of my teacher.

Am I wrong that 傳 is about dissemination?
朱熹四書章句集注 「傳，謂受之於師。習，謂熟之於己。」 

So 傳 means what you've received from your Master. James Legge's translation seems right.
