Gangling, rangy (5)
I believe the answer is:
lanky
I believe this is a double definition.
'gangling' is the first definition.
(I know that gangling can be written as lanky)
'rangy' is the second definition.
(I know that rangy can be written as lanky)
(Other definitions for lanky that I've seen before include "Tall, thin and loose-jointed" , "Tall and scrawny" , "Bony" , "Awkwardly long and thin" , "Awkwardly tall" .)
