Should regional dialects and local idioms be formally included in standard dictionaries?
The Oxford English Dictionary has officially added six Welsh English words and phrases to its collection. This update also included revisions to several existing entries related to Welsh language and culture.
Why it matters
The additions reflect a broader commitment to documenting regional English variations from Wales and across the globe. By formally recognizing these terms, the dictionary preserves and validates the unique linguistic contributions of Welsh English speakers.
The new entries include bachgen, boys bach, bwbach, in one's oils, now in a minute, and twpsyn. These terms have historical origins ranging from 1724 to 1941, grounding the update in long-standing regional linguistic usage.
The players
Oxford English Dictionary
The principal historical dictionary of the English language that provides a comprehensive record of words and their development.
The details
The update incorporates these Welsh terms as part of a wider World English project that also includes linguistic data from Bermuda, the Caribbean, East Africa, and New Zealand. Alongside the new entries, the dictionary revised existing terms such as ap, braggot, coracle, crwth, Gorsedd, and hwyl to reflect current lexicographical standards.
Timeline
1724: Earliest date recorded for the word bwbach.
1888: First attestation of the word bachgen.
1900: First recording of the phrase in one's oils.
1941: First date associated with the word twpsyn.
September 23, 2026: Official update release by the dictionary.
Culture Shift
The formal inclusion of these regional terms mirrors a larger shift in lexicography toward recognizing the validity of World English variations. This trend moves away from a singular standard of language and toward a more inclusive, pluralistic model of global communication.
Readers can now find formal definitions and etymological histories for common Welsh colloquialisms in the dictionary. This provides linguistic clarity for those encountering these terms in literature, media, or daily conversation.
The takeaway
Language evolves continuously, and the inclusion of regional dialect terms helps preserve the cultural identity of diverse communities. Keep an eye on dictionary updates if you are interested in how global dialects influence the evolution of the English language.
