In the morning, man starts to nod off after a coffee (9)
I believe the answer is:
americano
'coffee' is the definition.
(type of coffee)
'in the morning man starts to nod off after a' is the wordplay.
'in the morning' becomes 'am' (AM on a clock).
'man' becomes 'eric' (I've seen this before).
'starts to' says to take the initial letters.
'after' says to put letters next to each other.
The initial letters of 'nod off' is 'no'.
'no' after 'a' is 'ano'.
'am'+'eric'+'ano'='AMERICANO'
(Other definitions for americano that I've seen before include "drink" , "Style of coffee" , "Espresso diluted with hot water" .)
