Working on one line in poem, showing adaptability (9)
I believe the answer is:
versatile
'working on one line in poem showing adaptability' is the definition.
I can't tell whether this defines the answer.
'working on one line in poem' is the wordplay.
'working on' becomes 'at' (I've seen this in other clues).
'one' becomes 'i' (Roman numeral).
'line' becomes 'l' (used when specifying particular lines from a poem).
'in' is an insertion indicator.
'poem' becomes 'verse' (verse is a kind of poem).
'at'+'i'+'l'='atil'
'atil' placed inside 'verse' is 'VERSATILE'.
Can you help me to learn more?
(Other definitions for versatile that I've seen before include "Relatives able to do many things" , "Multiskilled" , "elastic!" , "Adaptable sort of relatives" , "Having many uses" .)
