Wait to play first shot (5)
I believe the answer is:
serve
I believe this is a quadruple definition!!
'wait' is the first definition.
(to wait on someone is to serve them)
'to play' is the second definition.
(serve is a kind of play)
'first' is the third definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'shot' is the fourth definition.
(I know that serve is a type of tennis shot)
Can you help me to learn more?
(Other definitions for serve that I've seen before include "Dish out food" , "Minister to" , "Wait - start the game" , "Work for; tennis stroke" , "Hand out, food or drink say" .)
