Murphy, for instance, has a right to public transport (5)
I believe the answer is:
tuber
'murphy for instance' is the definition.
I can't tell whether this defines the answer.
'a right to public transport' is the wordplay.
'a right' becomes 'r' (common abbreviation).
'to' says to put letters next to each other (I've seen this in other clues).
'public transport' becomes 'tube' (the London Underground is nicknamed the Tube. I am not sure about the 'public' bit.).
'r' put after 'tube' is 'TUBER'.
'has' acts as a link.
Can you help me to learn more?
(Other definitions for tuber that I've seen before include "A brute of a spud" , "Thickened underground stem" , "Type of plant, potato say" , "Underground stem, root" , "Fleshy root, vegetable say" .)
