Current treatment to prop up face and tongue (7)
I believe the answer is:
dialect
'tongue' is the definition.
(thesaurus)
'current treatment to prop up face' is the wordplay.
'current treatment' becomes 'ect' (ECT is an example. I am not sure about the 'current' bit.).
'to prop up' is a charade indicator (letters next to each other).
'face' becomes 'dial' (face of a clock).
'ect' after 'dial' is 'DIALECT'.
'and' is the link.
Can you help me to learn more?
(Other definitions for dialect that I've seen before include "Local idiom" , "talk from the regions" , "Manner of speaking" , "Regional form of word" , "Regional language form" .)
