Obvious mum or dad can support tutors lacking faith at heart (11)
I believe the answer is:
transparent
'obvious' is the definition.
(similar in meaning)
'mum or dad can support tutors lacking faith at heart' is the wordplay.
I cannot quite see how this works, but
'mum' could be 'parent' and 'parent' is found in the answer.
The remaining letters 'trans' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for transparent that I've seen before include "poor at lying" , "Open" , "Obvious - ingenuous" , "Sheer" , "unmistakable" .)
