Good luck with Monsieur Donut!
I can manage:-
Fluent franglais,
Rather rusty semaphore,
Limited fingerspelling in BSL
Greetings, thanks and the words of quite a few songs in Welsh, plus the conversation: "Sut dych chi?" followed by "Wedi blino." which has proved useful because it's almost always true. Duolingo changed from having a friendly user interface into something horrible after I learnt "Wedi blino" so I gave up. If anyone knows a good online Welsh course, do let me know.
