Space to attempt log (5)
I believe the answer is:
entry
'log' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe there's a link between them I don't understand?
'space to attempt' is the wordplay.
'space' becomes 'en' (in printing, a space as wide as a letter 'n').
'to attempt' becomes 'try' ('try' can be a synonym of 'attempt').
'en'+'try'='ENTRY'
Can you help me to learn more?
(Other definitions for entry that I've seen before include "Door; appearance" , "Record - number of contestants" , "vestibule" , "Ingress, portal" , "Admittance" .)
