Feudal lord of Chinese dynasty occupying Tien, oddly (5)
I believe the answer is:
thane
'feudal lord' is the definition.
'thane' can be an answer for 'lord' (I know that thane is a type of lord). I'm not sure about the 'feudal' bit.
'chinese dynasty occupying tien oddly' is the wordplay.
'chinese dynasty' becomes 'han' (I've seen this in another clue).
'occupying' means one lot of letters goes inside another (inserted letters occupy or enter the word).
'oddly' indicates alternate letters (letters in the odd-numbered positions are used).
The alternate letters of 'tien' are 'te'.
'han' inserted into 'te' is 'THANE'.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for thane that I've seen before include "baron once" , "Medieval lord" , "Scot who held land from the king" , "Anglo-Saxon aristocrat - old Scottish clan chief" , "Medieval Scottish clan chief" .)
