Spies Lee in with the model, most comatose (9)
I believe the answer is:
sleepiest
'most comatose' is the definition.
Both the answer and definition are superlative adjectives. Perhaps they are linked in a way I don't understand?
'spies lee in with the model' is the wordplay.
'in' is an insertion indicator.
'with' says to put letters next to each other.
'the model' becomes 't' (Ford Model T car).
'spies' enclosing 'lee' is 'sleepies'.
'sleepies'+'t'='SLEEPIEST'
Can you help me to learn more?
(Other definitions for sleepiest that I've seen before include "more tired than anyone else" , "most lethargic" .)
