Similar title makes an odd headline in the end (8)
I believe the answer is:
namesake
'similar title' is the definition.
'namesake' can be an answer for 'title' (thesaurus). I am not certain of the 'similar' bit.
'makes an odd headline in the end' is the wordplay.
'odd' indicates anagramming the letters.
'in the end' says to take the final letters.
The final letter of 'headline' is 'e'.
'makes'+'an'='makesan'
'makesan' anagrammed gives 'namesak'.
'namesak'+'e'='NAMESAKE'
Can you help me to learn more?
(Other definitions for namesake that I've seen before include "one similarly entitled" , "One is called after someone" , "As one David is to another David, say" , "One addressed in the same way" , "Make sane (anag.)" .)
