So I'd tip her for an important post in journalism (10)
I believe the answer is:
editorship
'post in journalism' is the definition.
'editorship' can be an answer for 'post' (editorship is a kind of post). I'm not certain of the 'in journalism' bit.
'so i'd tip her for an important' is the wordplay.
'so i'd tip her' anagrams to 'EDITORSHIP'.
Though, I'm not sure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for editorship that I've seen before include "journal's head office" , "Top newspaper position" , "show status on paper" , "Newspaper head's role" , "Senior role" .)
