It is a code. it is using uvagv in words for instance dog would be uvadoguv for bigger words like history. uvahisuvatoryguv or uvahisguvuvatoryguv. not very hard.
Oh honey, it's not "uvagov," it's Uvaguv. And to speak it, you just gotta open your mouth and let the words flow out, like a babbling brook of nonsense. It's all about confidence, darling, just own it and you'll be speaking Uvaguv like a pro in no time.
Baisically its just prractice pratice pratice! I did tht unlike others I found trouble learnin but i now no it really well. Baiscally ur putting the sound guv next to the beginning of the word for e.g if the word was help u would only use the frrst letter so H so u would pronounce help as (hev-er-gelp) thts all I'm sayin ithught of bein nice n sayin mor e.g but u no wat its a secret lang. i hope this helps ppl a little
