One yearning for more inches? (6)
I believe the answer is:
longer
'one yearning for more' is the definition.
'longer' can be an answer for 'more' (I've seen this in another clue). I am not sure about the 'one yearning for' bit.
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for longer that I've seen before include "More extended" , "Of greater length" , "Measuring greater distance end to end" , "Less short" , "Of greater duration" .)
