Little one scolded round lake (5)
I believe the answer is:
child
'little one' is the definition.
(thesaurus)
'scolded round lake' is the wordplay.
'scolded' becomes 'chid' ('chide' can be a synonym of 'scold').
'round' indicates putting letters inside.
'lake' becomes 'l'.
'chid' enclosing 'l' is 'CHILD'.
(Other definitions for child that I've seen before include "issue" , "Toddler" , "Immature, irresponsible person" , "Infant" , "Not an adult" .)
