Welsh settlement in Argentina) in 1865; it includes Spanish loanwords and terms for local features, but a survey in the 1970s showed that the language in Patagonia is consistent throughout the lower Chubut Valley and in the Andes. Subdialects exist within the main dialects (such as the Cofi dialect). The 1989 book () was accompanied by a cassette containing recordings of 14 different speakers demonstrating aspects of different regional dialects. The book also refers to the earlier Linguistic Geography of Wales (1973) as describing six different regions which could be identified as having words specific to those regions. In the 1970s, there was an attempt to standardise the Welsh language by teaching ("Living Welsh") – a colloquially-based generic form of Welsh. But the attempt largely failed because it did not encompass the regional differences used by Welsh-speakers. Registers Modern Welsh can be considered to fall broadly into two main registers—Colloquial Welsh () and Literary Welsh (). Colloquial Welsh is used in most speech and informal writing. Literary Welsh is closer to the form of Welsh standardised by the 1588 translation of the Bible and is found in official documents and other formal registers, including much literature. As a standardised form, literary Welsh shows little if any of the dialectal variation found in colloquial Welsh. Some differences include: Amongst the characteristics of the literary, as against the spoken language are a higher dependence on inflected verb forms, different usage of some of the tenses, less frequent use of pronouns (since the information is usually conveyed in the verb/preposition inflections) and a much lesser tendency to substitute English loanwords for native Welsh words. In addition, more archaic pronouns and forms of mutation may be observed in Literary Welsh. Examples of sentences in literary and colloquial Welsh The differences between dialects of modern spoken Welsh pale into insignificance compared to the difference between some forms of the spoken language and the most formal constructions of the literary language. The latter is considerably more conservative and is the language used in Welsh translations of the Bible, amongst other things – although the 2004 () is significantly less formal than the traditional 1588 Bible. Gareth King, author of a popular Welsh grammar, observes, “The difference between these two is much greater than between the virtually identical colloquial and literary forms of English.” A grammar of Literary Welsh can be found in A Grammar of Welsh
