Spanish architect inspired by oblong auditorium (5)
I believe the answer is:
gaudi
'spanish architect' is the definition.
'gaudi' can be an answer for 'architect' (I've seen this before). I am not sure about the 'spanish' bit.
'inspired by oblong auditorium' is the wordplay.
'inspired by' says the answer is hidden in the clue (the clue has breathed in or 'inspired' the answer).
'GAUDI' can be found hidden inside 'oblong auditorium'.
Can you help me to learn more?
(Other definitions for gaudi that I've seen before include "Architect of the Sagrada Familia church in Barcelona, d. 1926" , "Antonio ___, Barcelona's art nouveau architect" .)
