Hard rowing team in top position? (6)
I believe the answer is:
height
'top position?' is the definition.
'height' can be an answer for 'top' (I've seen this before). I am unsure of the 'position?' bit.
'hard rowing team' is the wordplay.
'hard' becomes 'h' (abbreviation used in pencil classifications).
'rowing team' becomes 'eight' (eight rowers).
'h'+'eight'='HEIGHT'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for height that I've seen before include "Distance form top to bottom" , "Loftiness" , "Altitude or elevation" , "part of a patient's statistics?" , "Crowning moment" .)
