Sounds like a greater number are travelling through Eastern European region (7)
I believe the answer is:
moravia
'region' is the definition.
(I know that Moravia is a region)
'sounds like a greater number are travelling through eastern european' is the wordplay.
I cannot quite understand how this works, but
'a' is found in the answer.
'number' could be 'vi' (VI is an example) and 'vi' is present in the answer.
'are' could be 'a' (short for 'are', historical unit of measurement) and 'a' is located in the answer.
The remaining letters 'mor' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for moravia that I've seen before include "Region in Czech Republic" , "part of Czech Republic" , "Italian writer - Czech region" , "Area of the Czech Republic" .)
