An inclination to enumerate? (4)
I believe the answer is:
list
I believe this is a double definition.
'an inclination' is the first definition.
(list can mean to tilt, lean or incline)
'enumerate?' is the second definition.
(I know that list is a more specific form of the action enumerate)
'to' acts as a link.
(Other definitions for list that I've seen before include "Italian port" , "Devoid of spirit or energy" , "Catalogue; tilt" , "choice" , "Consecutive series of items" .)
