Relatively apt to be looked up to? (6)
I believe the answer is:
taller
'relatively apt to be looked up to?' is the definition.
I can't tell whether this defines the answer.
'apt to be looked up to?' is the wordplay.
'apt' becomes 'er' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' means one lot of letters go next to another (I've seen this in other clues).
'be looked up to?' becomes 'tall' (I've seen this in another clue).
'er' put after 'tall' is 'TALLER'.
Can you help me to learn more?
(Other definitions for taller that I've seen before include "Higher in stature" , "Greater in stature" .)
