Trained, the least sporty people (8)
I believe the answer is:
athletes
'sporty people' is the definition.
'athletes' can be an answer for 'people' (athlete is a kind of person). I'm not certain of the 'sporty' bit.
'trained the least' is the wordplay.
'trained' indicates an anagram (to train can mean to grow something into a shape).
'the'+'least'='theleast'
'theleast' with letters rearranged gives 'ATHLETES'.
Can you help me to learn more?
(Other definitions for athletes that I've seen before include "sportspeople?" , "They engage in physical exercises and sports" , "Sportsmen and women" , "Sports contestants" , "Derval O'Rourke and Usain Bolt, say" .)
