Anybody know the difference between "committee" and "commission"?
anybody translates the question into Chinese will be BSed.
Hahaha.

A committee is "a body of persons delegated to consider,investigate,take action on,or report on some matter; especially :a group of fellow legislators chosen by a legislative body to give consideration to legislative matters" or "a self-constituted organization for the promotion of a common object".
A commission is "a group of persons directed to perform some duty" or "a government agency having administrative,legislative,or judicial powers" or "a city council having legislative and executive functions"
Generally they are similiar in meaning but one or the other would be used in different contexts.
I suggest to understand the difference it is best to look at the MISSION STATEMENTS of some "comittees" and "commissions" and then you can get a general idea of the difference.
