Listing all tables in schema along with synonyms ,if any

hi,

Please could someone help me with the following :-
Listing all tables in schema along with synonyms ,if any.

I have tried DBA_SYNONYMS , USER_SYNONYMS , SYNONYMS etc.

I think when i am using the above i am missing those tables which are not having
any SYNONYMS. i need a complete list of all tables on a schema along with synonyms if any. If it is not there then it should report blank

please advise

thanks
