This longitudinal research provides further insights into their continuing language journeys, and indicates there has been a sustained reduction in this group's use of Welsh by 2016/2017 due to factors relating to fluency, confidence and a lack of opportunities to use Welsh. However, the results indicate that new speakers play an important role in influencing family language transmission and in increasing language awareness within the workplace. This paper calls for further longitudinal research on new Welsh speakers' language journeys so that this group may be appropriately supported as they make a crucial contribution to language revitalisation in Wales.
