Architect Jones (5)
I believe the answer is:
inigo
'architect jones' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for inigo that I've seen before include "Adverb giving emphasis (grammar)" , "___ Jones, English architect and stage designer" , "- Jones, Eng. architect" , "Man" , "one of the Joneses" .)
