Liam's type of religion (5)
I believe the answer is:
islam
'religion' is the definition.
(Islam is an example)
'liam's type' is the wordplay.
'type' is an anagram indicator.
'liams' anagrammed gives 'ISLAM'.
'of' is the link.
(Other definitions for islam that I've seen before include "Adherents of a religion" , "Belief" , "Faith with five pillars" , "Koran its scripture" , "Creed" .)
