About the Arddulliadur

The Arddulliadur brings together various pieces of advice and guidance regarding language and style. The Arddulliadur is published in Welsh only.

The Arddulliadur was developed to provide advice and guidance to those translating general texts, and helps to ensure consistency across the Government’s work. Translators working on behalf of the Welsh Government are asked to follow the guidance given here.

The advice may also be useful for other translators and indeed for anyone who drafts Welsh-language texts.

The articles in the Arddulliadur are grouped under three sections. Below is a short explanation of what is included in each section. Of course, there will be some overlap, and some articles appear under more than one heading.

Correct Welsh

These are mainly points of grammar and orthography. The main reference materials used in deciding on the advice to give are Gramadeg y Gymraeg (1996) Peter Wynn Thomas, Geiriadur Prifysgol Cymru and Orgraff yr Iaith Gymraeg (1987).

Consistency of style

These are matters that may be dealt with in several, equally valid, ways. This section specifies what we wish translators to use when translating material for the Welsh Government, in order to ensure consistency of style throughout our work. 

Advice on good translation

In this section, we give advice on issues that could be problematic or difficult to translate.
