Well said and a useful clarification.


Does that mean (since cel-gaulish was not on your irregular list, and also given that cel is a registered tag and gaulish is five-to-eight letters) that I can now write things like 

cel-GRK-gaulish

to describe, say a gaulish legend on a coin, written in ancient greek script?
