At festive occasions a journalist is treated (5)
I believe the answer is:
dosed
'is treated' is the definition.
(similar in meaning)
'at festive occasions a journalist' is the wordplay.
'at' says to put letters next to each other.
'festive occasions' becomes 'dos' (do is a kind of occasion. I am not sure about the 'festive' bit.).
'a journalist' becomes 'ed' (short for editor).
'dos' next to 'ed' is 'DOSED'.
Can you help me to learn more?
(Other definitions for dosed that I've seen before include "Gave medicine to" , "Given a drug" , "Given medicine" , "Given shot" , "Administered a drug to" .)
