Tree found in Pennsylvania by character with roots to Ottoman Empire (5)
I believe the answer is:
pasha
'character with roots to ottoman empire' is the definition.
I know that 'ottoman' relates to this answer.
'tree found in pennsylvania' is the wordplay.
'tree' becomes 'ash' (ash is a kind of tree).
'found in' is an insertion indicator.
'pennsylvania' becomes 'PA'.
'ash' placed into 'pa' is 'PASHA'.
'by' acts as a link.
Can you help me to learn more?
(Other definitions for pasha that I've seen before include "High-ranking Turk" , "Ottoman governor" , "Muslim dignitary" , "foreign officer" , "Turkish high-ranker" .)
