Communicate with disheartened Turk about Arabic article (4)
I believe the answer is:
talk
'communicate with' is the definition.
(thesaurus)
'disheartened turk about arabic article' is the wordplay.
'disheartened' suggests removing the centre (the middle or heart is removed).
'about' means one lot of letters goes inside another.
'arabic article' becomes 'al' (I am not sure about this - if you are sure you should believe this answer much more).
'turk' with its middle taken out is 'tk'.
'tk' enclosing 'al' is 'TALK'.
Can you help me to learn more?
(Other definitions for talk that I've seen before include "Discourse" , "Communicate" , "Rabbit" , "Conversation" , "Utter" .)
