People see oddly neglected Olympic event (4)
I believe the answer is:
epee
'olympic event' is the definition.
(I've seen this before)
'people see oddly neglected' is the wordplay.
'oddly neglected' indicates alternate letters (letters in odd-numbered positions removed).
'people'+'see'='peoplesee'
The alternate letters of 'peoplesee' are 'EPEE'.
(Other definitions for epee that I've seen before include "sports equipment" , "Duelling weapon" , "Fencing sword similar to a foil" , "Pointed weapon" , "Fencer's weapon" .)
