Religious portrait Tees does? (4)
I believe the answer is:
icon
'religious portrait' is the definition.
'icon' can be an answer for 'portrait' (I've seen this before). I also know that 'religious' relates to this answer.
'tees does?' is the wordplay.
'tees' becomes 'I' (where the crossword setter is 'Tees').
'does?' becomes 'con' (I am not sure about this - if you are sure you should believe this answer much more).
'i'+'con'='ICON'
Can you help me to learn more?
(Other definitions for icon that I've seen before include "Religious image or computer symbol" , "Representative symbol, may be on computer screen" , "A good figure" , "work of art" , "Symbolic person or image" .)
