Rank Keith last in project, without further ado (4,4,4)
I believe the answer is:
just like that
'without further ado' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'rank keith last in project' is the wordplay.
'rank' indicates anagramming the letters (a rank or rotten spelling of the letters).
'in' indicates putting letters inside.
'project' becomes 'jut' (project can mean to jut out).
'keith'+'last'='keithlast'
'keithlast' anagrammed gives 'stliketha'.
'stliketha' going inside 'jut' is 'JUST LIKE THAT'.
Can you help me to learn more?
(Other definitions for just like that that I've seen before include "Out of the blue" , "In a twinkling" , "straight away" , "Exactly so" , "What Tommy Cooper used to say" .)
