Dw i'n gweithio fel technegydd mewn ysgol iaith Cymraeg, I work as a technician in a Welsh Language school.
Despite not being a welsh speaker (I dropped welsh at year 9 when I was in school for German, something in the benefit of hindsight that was daft, considering I have no intention of ever going to or working in Germany). I am learning as an adult now via Cymraeg i Oedolion -
Cymraeg i Oedolion | Welsh for Adults
The school I work in supports me in learning Welsh (the immersion of the environment, is very good for picking up the vocabulary)and the class is not expensive - £100 for a years lessons on the intensive course(2 hours 2 nights a week), which the school reimburse me for, I am nearing the end of year one now, I estimate it will take about 3 years to get up to fluency where I work.
