since there is usually partial mutual intelligibility. Since there is a very high level of mutual intelligibility between contemporary speakers of Scots in Scotland and in Ulster (Ulster Scots), and a common written form was current well into the 20th century, the two varieties have usually been considered as dialects of a single tongue rather than languages in their own right; the written forms have diverged in the 21st century. The government of the United Kingdom "recognises that Scots and Ulster Scots meet the Charter's definition of a regional or minority language". Whether this implies recognition of one regional or minority language or two is a question of interpretation. Ulster Scots is defined in legislation (The North/South Co-operation (Implementation Bodies) Northern Ireland Order 1999) as: the variety of the Scots language which has traditionally been used in parts of Northern Ireland and in Donegal in Ireland. While in continental Europe closely related languages and dialects may get official recognition and support, in the UK there is a tendency to view closely related vernaculars as a single language. Even British Sign Language is mistakenly thought of as a form of 'English' by some, rather than as a language in its own right, with a distinct grammar and vocabulary. The boundaries are not always clear cut, which makes it hard to estimate numbers of speakers. Hostility In Northern Ireland, the use of Irish and Ulster Scots is sometimes viewed as politically loaded, despite both having been used by all communities in the past. According to the Northern Ireland Life and Times Survey 1999, the ratio of Unionist to Nationalist users of Ulster Scots is 2:1. About 1% of Catholics claim to speak it, while 2% of Protestants claim to speak it. The disparity in the ratios as determined by political and faith community, despite the very large overlap between the two, reflects the very low numbers of respondents. Across the two communities 0% speak it as their main language at home. A 2:1 ratio would not differ markedly from that among the general population in those areas of Northern Ireland where Scots is spoken. Often the use of the Irish language in Northern Ireland has met with the considerable suspicion of Unionists, who have associated it with the largely Catholic Republic of Ireland, and more recently, with the republican movement in Northern Ireland itself. Catholic areas of Belfast have street signs in
