I see Francach also means rat. Apparently (by which I mean this was the first thing I saw when I Googled it but I looked no further into it than that) this is because people believed the rat was brought over here during the Norman invasion.
I said "The French are in Germany", wanted 'is' instead of 'are', not sure who's right?!
"an Francach" is a single Frenchman or French person, so "is" is the correct form of the verb for the 3rd person singular.
"The French": na Francaigh/muintir na Fraince
well, that's a nice change for once :p
