No good straddling beam? On the contrary, very leggy (5)
I believe the answer is:
rangy
'leggy' is the definition.
Both the definition and answer are adjectives. Perhaps they are linked in a way I don't understand?
'no good straddling beam? on the contrary' is the wordplay.
I cannot quite see how this works, but
'no' could be 'n' (common abbreviation) and 'n' is found in the answer.
'good' could be 'g' (abbreviation) and 'g' is found in the answer.
'beam?' could be 'ray' (synonyms) and 'ray' is present in the leftover letters.
No letters remain.
This explanation may well be incorrect...
'very' acts as a link.
Can you help me to learn more?
(Other definitions for rangy that I've seen before include "Long-legged" , "Antipodean mountain" , "Gangling" , "Tall and thin" , "with gangly limbs" .)
