Personage at last opening show (5)
I believe the answer is:
event
'show' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'personage at last opening' is the wordplay.
'at last' suggests the final letters.
'opening' becomes 'vent' (vent is a kind of opening).
The last letter of 'personage' is 'e'.
'e'+'vent'='EVENT'
Can you help me to learn more?
(Other definitions for event that I've seen before include "Something happening" , "Something that happens - part of a programme?" , "A noteworthy happening or occurrence" , "Occurren" , "Happening, noteworthy perhaps" .)
