Lifeless in a team in chaos (9)
I believe the answer is:
inanimate
'lifeless' is the definition.
(similar in meaning)
'in a team in chaos' is the wordplay.
'chaos' indicates anagramming the letters.
'team'+'in'='teamin'
'teamin' anagrammed gives 'nimate'.
'in'+'a'+'nimate'='INANIMATE'
(Other definitions for inanimate that I've seen before include "unable to move" , "spiritless" , "lacking in spirit" , "Not alive" , "wooden" .)
