Bit of speech therapy - German, it's true (4)
I believe the answer is:
echt
'true' is the definition.
(I've seen this before)
'bit of speech therapy german' is the wordplay.
'bit of' indicates a hidden word.
'ECHT' is hidden in the letters of 'speech therapy german'.
'it's' is the link.
(Other definitions for echt that I've seen before include "Genuine (German)" , "Genuine - authentic" , "Really" , "German's real" , "Genuine (Ger.)" .)
