Being talented, I burst into song at the end of concert (9)
I believe the answer is:
promising
'being talented' is the definition.
Both the definition and answer are adjectives. Maybe there's an association between them I don't understand?
'i burst into song at the end of concert' is the wordplay.
'burst into song' becomes 'sing'.
'at the end of' means one lot of letters go next to another (some letters go at the end of others).
'concert' becomes 'prom' (abbreviation for promenade concert).
'i'+'sing'='ising'
'ising' put after 'prom' is 'PROMISING'.
Can you help me to learn more?
(Other definitions for promising that I've seen before include "Showing great potential" , "Favourable -- hopeful" , "Encouraging" , "Giving one's word" .)
