Rough meadow by the railway (8)
I believe the answer is:
leathery
'rough' is the definition.
Both the answer and definition are adjectives. Maybe they are linked in a way I don't understand?
'meadow by the railway' is the wordplay.
'meadow' becomes 'lea' (a lea is a grassy area).
'by' is a charade indicator (letters next to each other).
'railway' becomes 'ry' (abbreviation for railway).
'lea'+'the'+'ry'='LEATHERY'
Can you help me to learn more?
(Other definitions for leathery that I've seen before include "Tough, wrinkled (skin)" , "Like tough skin" , "as old balls?" , "Tough like tanned hide" , "Tough textured" .)
