Nocha chummae cách is cách.
Nocha chummae cách is cách.
(is not * same * everyone * and * everyone)
Everyone is not the same.
The line is found in the second quatrain of three that make up a composition which Meyer edited in ZCP 12 under the title "Wirtshausreime". That everyone is not the same seems like an obvious observation. In context, however, the meaning is probably more like "everyone is not equally admirable". The lines which come just before say:
"Teccait âigid, fâcboit ail
saigit go glain nGâidil ngil"
They come to the fore, they leave disgrace,
they purely seek the bright Gaels
