Points to a piece of work by a Spaniard (5)
I believe the answer is:
senor
'a spaniard' is the definition.
('mister' in Spanish)
'points to a piece of work by' is the wordplay.
'points' becomes 'se' (two compass points).
'to a piece of work' becomes 'nor' (I am not sure about this - if you are sure you should believe this answer much more).
'by' says to put letters next to each other.
'se'+'nor'='SENOR'
Can you help me to learn more?
(Other definitions for senor that I've seen before include "Title of a Spanish-speaking man" , "Spanish for Mr" , "address on the Costa del Sol" , "Spanish form of address" , "European title" .)
