The Oxford English Dictionary (OED) has added Welsh words to its latest update.

The OED's update, released on Thursday, September 19, added a variety of Welsh words, including "ych a fi", a Welsh interjection of disgust or disdain.

The update also featured "iechyd da", a Welsh term meaning "cheers" or "good health", commonly used in social drinking contexts.

The inclusion of these words is part of the OED's commitment to documenting the diversity of English.

The dictionary aims to keep pace with the rapidly developing vocabulary of Englishes worldwide by implementing a new system of regular World English updates.

This month’s update also features new words from Guyana, East Africa, and New Zealand.

The OED has been undertaking various large-scale editorial projects focusing on different varieties of English spoken around the world for several years.

This new approach will ensure the timely and consistent monitoring of all major varieties of English covered by the dictionary.

The OED's update also included a collection of words relating to beer, in time for the Munich-based Oktoberfest, which celebrates Bavarian culture and beer.

The festival kicked off on Saturday, September 21.

The new beer-related words reflect the social aspect of beer consumption, with terms like "beer league", "beer-drink", and "beer-up" being added.

These terms are used in different contexts around the world, reflecting the global nature of the English language.

The OED's update also highlighted the downside of excessive beer consumption, with terms like "beer bombard" and "beer hound" being added to describe those who drink beer to excess.

The update also included the term "beer baron", a successful or powerful figure in the beer industry, and updated "beerage", a term used in humorous and satirical contexts to describe wealthy, powerful, or influential people associated with brewing or the beer industry.

The OED's update is a reflection of the ever-evolving English language, with new words and phrases constantly being added to reflect changes in society and culture.

The OED will continue to monitor and update its entries to ensure it remains a comprehensive record of the English language.
