Borrowed from German, it’s true (4)
I believe the answer is:
echt
'true' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for echt that I've seen before include "True" , "Authentic and typical" , "Genuine -- honest" , "Genuine - authentic" , "Genuine (Ger.)" .)
