Admission, access (5)
I believe the answer is:
entry
I believe this is a double definition.
'admission' is the first definition.
(I've seen this before)
'access' is the second definition.
(I know that entry is a type of access)
(Other definitions for entry that I've seen before include "all runners" , "Access point" , "Competitor" , "field" , "Gate" .)
