What it costs to get Richard started in the school's gym (5)
I believe the answer is:
price
'what it costs' is the definition.
(I've seen this in another clue)
'richard started in the school's gym' is the wordplay.
I cannot quite see how this works, but
'richard' could be 'ric' (short form) and 'ric' is found within the answer.
'gym' could be 'pe' (short for Physical Education) and 'pe' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to get' acts as a link.
Can you help me to learn more?
(Other definitions for price that I've seen before include "Amount for which a thing is sold" , "Amount needed to purchase something" , "Monetary value" , "Cost of purchase" , "What has to be paid" .)
