Article is elevated in cathedral without difficulty (6)
I believe the answer is:
easily
'without difficulty' is the definition.
(synonyms)
'article is elevated in cathedral' is the wordplay.
'article' becomes 'a' (the indefinite article in English).
'elevated' says the letters should be written in reverse (down clues only).
'in' is an insertion indicator.
'cathedral' becomes 'ely' (cathedral city in Cambridgeshire).
'is' written backwards gives 'si'.
'a'+'si'='asi'
'asi' placed within 'ely' is 'EASILY'.
(Other definitions for easily that I've seen before include "Effortlessly" , "no problem!" , "Comfortably" , "Without difficulty or effort" , "with little effort" .)
