Sefydlwyd IAITH yn 1993 i gynnig cyngor proffesiynol er mwyn hyrwyddo'r Gymraeg a datblygu arferion dwyieithog. Mae rôl, maint a dylanwad y cwmni wedi tyfu'n gyson ers hynny. Mae ein cleientiaid yn cynnwys prif gyrff cyhoeddus Cymru a sefydliadau mewn cymunedau iaith eraill ym Mhrydain ac Ewrop. Established in 1993 to help organisations in Wales promote the use of Welsh and develop bilingual practices, IAITH has found that its role, capacity and influence have grown steadily over the years. Our clients include Wales' leading public bodies as well as organisations serving other language communities in Britain and Europe.
