Dwelly's preface is of particular interest to the student of Scottish Gaelic, since many of the difficulties which he faced then are also applicable to today's Scottish Gaelic. Scottish Gaelic speakers were generally not taught to read and write in their native language and were therefore unable to provide correct spelling, which created enormous difficulties in preparing the dictionary. Scottish Gaelic speakers were also often reluctant to engage in Scottish Gaelic conversation with students of Scottish Gaelic such as Dwelly, generally preferring to speak to him in English. Dwelly often had to pose as a native speaker of Scottish Gaelic in order to obtain the opportunity to further his knowledge and understanding of colloquial Scottish Gaelic.
