Confirm tea laid out after five (8)
I believe the answer is:
validate
'confirm' is the definition.
(validating is a kind of confirming)
'tea laid out after five' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'after' says to put letters next to each other.
'five' becomes 'v' (roman numeral).
'tea'+'laid'='tealaid'
'tealaid' anagrammed gives 'alidate'.
'alidate' put after 'v' is 'VALIDATE'.
(Other definitions for validate that I've seen before include "Confirm or authenticate" , "Confirm truth of (item)" , "Confirm correctness of" , "Verify" , "Declare legally acceptable" .)
