Borrowed from German, it's true (4)
I believe the answer is:
echt
'true' is the definition.
(I've seen this before)
'borrowed from german it's' is the wordplay.
I cannot quite understand how this works, but
'it' could be 't' (abbreviation. e.g. in 'tis) and 't' is found in the answer.
The remaining letters 'ech' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
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.)" .)
