Look by English ship for titled female (7)
I believe the answer is:
duchess
'titled female' is the definition.
(I've seen this before)
'look by english ship' is the wordplay.
'look by' becomes 'duch' (I can't justify this - if you can you should believe this answer much more).
'english' becomes 'E' (abbreviation).
'ship' becomes 'SS' (prefix in ship names eg SS Great Britain).
'duch'+'e'+'ss'='DUCHESS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for duchess that I've seen before include "Great lady" , "Female aristocrat" , "Wife of a duke" , "Titled lady" , "Noblewoman" .)
