Too fond of hopeless tin god (6)
I believe the answer is:
doting
'too fond' is the definition.
'doting' can be an answer for 'fond' (synonyms). I'm not sure about the 'too' bit.
'hopeless tin god' is the wordplay.
'hopeless' indicates anagramming the letters.
'tin'+'god'='tingod'
'tingod' is an anagram of 'DOTING'.
'of' is the link.
Can you help me to learn more?
(Other definitions for doting that I've seen before include "Overly fond of, say spouse" , "Excessively fond" , "excessive worship" , "Foolishly loving and indulgent" , "Showing great fondness as for a spouse" .)
