If 'sit nro kit' stands for 'clouds pour down';
'nro bsi mit' stands for 'down he goes' and
'bsi nro zpi' stands for 'died down he',
which word would means 'goes' ?
In the first and second statements, the common code word is 'nro' and the common word is 'down'.
So, 'nro' means 'down'.
In the second and third statements, the coommon code word is 'bst' and the common word is 'he'.
So 'bsi' means 'he'.
Thus, in the second statements, 'mit' means 'goes'.
