More vulgar chap appropriating grand language (3,6)
I believe the answer is:
low german
'language' is the definition.
(Low German is an example)
'more vulgar chap appropriating grand' is the wordplay.
I cannot quite understand how this works, but
'more' could be 'm' and 'm' is located in the answer.
'vulgar' could be 'low' and 'low' is located in the answer.
'grand' could be 'g' (G is short for grand as in a thousand) and 'g' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for low german that I've seen before include "language" , "European dialect" .)
