A day to support Saint David, for example (6)
I believe the answer is:
statue
'david for example' is the definition.
I can't tell whether this definition defines the answer.
'a day to support saint' is the wordplay.
'day' becomes 'tue' (abbreviation for Tuesday).
'to support' says to put letters next to each other (in a down clue, some letters hold others up).
'saint' becomes 'st' (abbreviation).
'a'+'tue'='atue'
'atue' after 'st' is 'STATUE'.
Can you help me to learn more?
(Other definitions for statue that I've seen before include "Sculptured person" , "Carved representation" , "Artistic work" , "Figurine" , "Noble's rank or dignity" .)
