Teased medic on deck, drunk (6)
I believe the answer is:
mocked
'teased' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Perhaps there's an association between them I don't understand?
'medic on deck drunk' is the wordplay.
'medic' becomes 'mo' (medical officer).
'on' says to put letters next to each other.
'drunk' indicates an anagram.
'deck' with letters rearranged gives 'cked'.
'mo'+'cked'='MOCKED'
Can you help me to learn more?
(Other definitions for mocked that I've seen before include "made fun of" , "Derided, scoffed at" , "Imitated with derision" , "Scorned" , "Ridiculed" .)
