Live BA, oddly, capable of existing (6)
I believe the answer is:
viable
'capable of existing' is the definition.
I can't tell whether this defines the answer.
'live ba oddly' is the wordplay.
'oddly' indicates anagramming the letters (letters in an odd order).
'live'+'ba'='liveba'
'liveba' anagrammed gives 'VIABLE'.
Can you help me to learn more?
(Other definitions for viable that I've seen before include "Feasible" , "Practicable, able to be done successfully" , "(Of plan) capable of working" , "Able to function, grow normally" , "Having a chance of success" .)
