Will i need to learn welsh?

No. Only about 20% of people in Wales speak Welsh (but they will also speak English) and everything that is in Welsh will also be English. It might be worth learning a few basics, but you probably won't even use that. Don't worry about your accent - nealy everyone in Wales will be familiar with the Irish accent.

How old are you? You don't have to learn Welsh unless you're attending a state school and are aged 16 or younger. 99% of Welsh people speak English perfectly, so they will have no trouble understanding your accent. Yes, everything is in Welsh, road-signs etc., but they're also in English, and few people actually pay attention to the Welsh. Hope you enjoy it here.

hee... what? i am lost.... you told us that you are not even 18 and you are going with your boyfriend to wales to study?... we lost information.... most countries dont give rights people who are under 18 then how come u got right to go away with boyfriend.... to your answer... No really you don't need to learn its not required but its recommended since everyone talk in welsh well teachers and educated talk in english but normal people dont and you need to have a translator around to understand better.

No, everything is not in Welsh, people will understand your english, I expect

No you wont. Few Welsh people even speak Welsh and even if they do 99% of the time English is still their first language.

You will figure it out when you get there.

yes

Ask your lad, lassie.
