Function takes in first chapel in Vatican (7)
I believe the answer is:
sistine
'function takes in first chapel in vatican' is the definition.
I can't judge whether this definition defines the answer.
'function takes in first' is the wordplay.
'function' becomes 'sine' (mathematical function).
'takes in' means one lot of letters goes inside another.
'first' becomes 'ist' (ist resembles 1st).
'sine' placed around 'ist' is 'SISTINE'.
Can you help me to learn more?
(Other definitions for sistine that I've seen before include "Famous Chapel in Vatican with Michelangelo paintings" , "-- Chapel (in Rome)" , "Vatican chapel name" , "Chapel with stunning ceiling" .)
