Second charity event the Scottish miss (5)
I believe the answer is:
morag
'the scottish miss' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'second charity event' is the wordplay.
'second' becomes 'mo' (both are short periods of time).
'charity event' becomes 'rag' (rag is a term for a charitable student society).
'mo'+'rag'='MORAG'
Can you help me to learn more?
(Other definitions for morag that I've seen before include "Scottish girl" , "Girl in Scotland" , "Scottish girl's name" , "Second-most famous monster supposedly living in a loch in Scotland" .)
