Kindly advise what is the difference between:
– Ayatollah
– Ayatollah Al-Uzma
– Marji’a
– Marji’a Taqleed
– Marji’a A’alam

Ayatollah is a mujtahid but not necessarily a marja

Ayatollah Uzma is a mujtahid who has declared his marjaiya

Marja and marja taqleed are the same thing meaning they are a mujtahid who have people following them in Islamic Laws

Marja Aalam means the most knowledgeable marja
