Ulster Scots Gregg was keen on researching the Ulster-Scots language and dedicated much of his research time on linguistic analysis and the application of his research. His work was quite extensive and widely published. See the Publications list for more information on his publications. While on sabbatical from UBC in 1960, Gregg travelled back to
Ulster and participated in the conference inaugurating the Ulster Dialect Archive at the Ulster Folk Museum (now the
Ulster Folk and Transport Museum) in 1960. From 1960 to 1963, he also finished his doctoral fieldwork. He travelled throughout the Ulster countryside and interviewed older traditional speakers. This fieldwork culminated in a widely revered map with precise detail on the geographical boundaries of the Ulster-Scots language. “He was the first to demonstrate that Ulster-Scots was spoken in the eastern part of
County Donegal in the
Republic of Ireland and was thus international.” This map is still used today, although some more recent work has shown that there are areas, such as south-west Tyrone, that have Ulster Scots characteristics even though they were not categorised as Ulster Scots by Gregg.
Ulster-Scots orthography Also starting in the 1960s, Gregg began to devise an orthography for Ulster-Scots. This orthography was based on Gregg's extensive fieldwork in the province. “In this process he produced transcriptions of local Ulster-Scots texts, or in some cases Ulster-Scots versions of English texts, to test and demonstrate various conventions.” Near the end of his life he shared his work with the Ulster Folk and Transport Museum's Concise Ulster Dictionary project, which ran from 1989–96. He was also hopeful that the new Ulster-Scots Language Society and Ulster-Scots Academy (created in 1994) would find his work useful for the Academy's language development work.
Canadian English In 1957, Gregg made a phonological assessment of
Vancouver, BC, speech in 1957. In the late 1960s and early 1970s, Gregg conducted a survey of southern British Columbia English. The results were not published, but can be found in two M.A. theses.
Survey of Vancouver English, 1976-1984 In 1976, Gregg and a team of students, featuring Margaret Murdoch, Gaelan Dodds de Wolf, and Erika Hasebe-Ludt, embarked on a major project surveying the English spoken by native English speakers born in Vancouver, BC, Canada. It began with a small preliminary survey from 1976 to 1978 of 60 individuals. This survey was then incorporated with the larger Survey of Vancouver English that ran from 1978 to 1984. The larger survey included the individuals from the preliminary survey as well as 240 other individuals. After its completion, it was a primary informant for de Wolf's study comparing English in Vancouver with that of English in Ottawa. The survey was funded by grants from the
Social Sciences and Humanities Research Council and other foundations. ==Awards and recognition==
