The Association of Welsh Translators and Interpreters is a group of people who work with language. They mostly work with the Welsh language, which is a language spoken in Wales.
Translators are like language teachers who help people understand words or phrases in a different language. For example, if you don't know what "dwi'n hoffi dawnsio" means (which is "I like to dance" in Welsh), a translator could help you understand it.
Interpreters, on the other hand, are like language coaches who help people understand what others are saying in a different language. For example, if someone is speaking Welsh to you and you don't understand it, an interpreter could help you understand what they are saying by translating it into English for you.
The Association of Welsh Translators and Interpreters is a group of people who work together to make sure that people who speak Welsh and people who don't speak Welsh can communicate with each other easily. They help people who need translators or interpreters find the right ones for their needs, and they also help translators and interpreters in their profession by providing important resources and support.
In summary, the Association of Welsh Translators and Interpreters is a group of helpful people who make sure that the Welsh language can be easily understood by everyone who needs it.
