Lifeless? Precisely! (4)

I believe the answer is:

dead

I believe this is a double definition.

'lifeless?' is the first definition.
(similar in meaning)

'precisely' is the second definition.
(thesaurus)

(Other definitions for dead that I've seen before include "Six feet under" , "Devoid of life" , "Stiff - bereft of life" , "cold" , "Late; exact" .)

I've seen this clue in the Evening Standard.
