Pride altered innate conception of something that is perfect (5)
I believe the answer is:
ideal
'is perfect' is the definition.
(similar in meaning)
'pride altered innate conception of something' is the wordplay.
'IDEAL' is hidden in amongst the letters.
But, I am unsure how the hidden word is indicated.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for ideal that I've seen before include "To which one aspires" , "Exemplar" , "superb specimen" , "Model of excellance" , "faultless" .)
