Fielder's skill is absent in this sport (8)
I believe the answer is:
throwing
'fielder's skill' is the definition.
The answer and definition are not the same part of speech.
'is absent in this sport' is the wordplay.
'absent in' suggests deleting specific letters.
'sport' becomes 'rowing' (rowing is a kind of sport).
'this' with 'is' taken away is 'th'.
'th'+'rowing'='THROWING'
Can you help me to learn more?
(Other definitions for throwing that I've seen before include "Puzzling" , "Projecting through the air" , "Propelling through the air" , "Chucking; unsettling" .)
