Glorified marriage commitment created falsehood to protect son (8)
I believe the answer is:
idolised
'glorified marriage commitment created' is the definition.
I can't judge whether this definition defines the answer.
'falsehood to protect son' is the wordplay.
I cannot quite understand how this works, but
'son' could be 's' (genealogical abbreviation for son) and 's' is present in the answer.
'falsehood' could be 'lie' (lie is a kind of falsehood) and 'lie' is present in the remaining letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for idolised that I've seen before include "Worshipped, say graven image" , "Treated like a pop star" , "Adored and worshipped" , "Hero-worshipped" , "Worshipped like graven image" .)
