Smith, for example, to endure celebrity (4,4)
I believe the answer is:
last name
'smith' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'to endure celebrity' is the wordplay.
'to endure' becomes 'last' ('last' can be a synonym of 'endure').
'celebrity' becomes 'name' (as in a 'big name').
'last'+'name'='LAST NAME'
'for example' acts as a link.
Can you help me to learn more?
(Other definitions for last name that I've seen before include "Part of appellation denoting family" , "Family identifier" , "Smith, say" , "Final appellation held by all members of a family" .)
