My editing

We absolutely encourage foreign words. I was myself working on French and Haitian Creole before my long hiatus from Wiktionary. But if you don't know the language well, be sure that your contribution is correct by checking other sources before you add it. There are only a handful of Irish editors, so there are not that many people available for fixing mistakes.

Overall, Wiktionary has almost as many articles as Wikipedia, and a small fraction of the number of editors, so we can't check every entry for correctness. The responsibility is more on the creators of entries to verify that they are correct.
