What is the difference between 都 and 所有?
I came across these words (都 and 所有) while doing Rosetta Stone exercises. Both appear to mean "all," but I am not sure in which case I should use one or the other. Please explain the difference and give me some examples of how to use each one.
Thank you.

Question

Answer

"都" is an adverb, It just like both.It usually use with 有.Maybe your question is compare 都有and所有
For example,我和爸爸都有一辆车
I and my father both have a car
"所有" is an adjective, It just like all 
For example 所有人都有眼睛

Answer

Like what Lily says, 都 is used before a verb, while 所有 a noun.
