Perhaps meet five out of seventeen (5)
I believe the answer is:
event
'perhaps meet five out' is the definition.
The answer and definition can be both acts as well as being singular nouns.
Maybe there's an association between them I don't understand?
'of seventeen' is the wordplay.
'of' indicates the answer is hidden within the clue.
'EVENT' can be found hidden inside 'seventeen'.
Can you help me to learn more?
(Other definitions for event that I've seen before include "tournament" , "High jump, say" , "Significant happening" , "Incident, occurrence" , "Particular happening" .)
