Feisty female Doctor Who at last seen in play (6)
I believe the answer is:
tomboy
'feisty female doctor who at last seen in play' is the definition.
'tomboy' can be an answer for 'feisty female'. I'm not certain of the remainder of the definition.
'female doctor who at last seen in play' is the wordplay.
'female doctor' becomes 'mb' (Bachelor of Medicine, Medicinae Baccalaureus. I am not sure about the 'female' bit.**).
'at last' indicates one should take the final letters.
'seen in' means one lot of letters goes inside another.
'play' becomes 'toy' ('toy' can be a synonym of 'play').
The last letter of 'who' is 'o'.
'mb'+'o'='mbo'
'mbo' placed within 'toy' is 'TOMBOY'.
Can you help me to learn more?
(Other definitions for tomboy that I've seen before include "girl behaving boisterously" , "Girl with the character of a lad" , "Hoyden" , "Wild, boisterous girl" , "Girl said to be exhibiting boyish behaviour" .)
