Am as keen to gain a similar title (8)
I believe the answer is:
namesake
'title' is the definition.
(thesaurus)
'am as keen to gain a similar' is the wordplay.
'am as keen' can be anagrammed to 'NAMESAKE'.
However, I'm not clear how this is indicated.
Can you help me to learn more?
(Other definitions for namesake that I've seen before include "one similarly entitled" , "Appellation sharer" , "One with the same appellation" , "Make sane (anag.)" , "One addressed in the same way" .)
