Always a lofty newspaper (2,3,5)
I believe the answer is:
at all times
'always' is the definition.
(synonyms)
'a lofty newspaper' is the wordplay.
'lofty' becomes 'tall' (synonyms).
'newspaper' becomes 'times' (The Times is an example).
'a'+'tall'+'times'='AT ALL TIMES'
(Other definitions for at all times that I've seen before include "never failing to appear" , "Always" , "Constantly" .)
