The Manx orthography was developed by people who were unaware of traditional Gaelic orthography, as they had learned literacy in Welsh and English (the initial development in the 16th century), then only English (later developments). Therefore, the orthography is based on early Modern English pronunciation, and to a small extent Welsh, rather than from a pan-Gaelic point of view. The result is an inconsistent and only partially phonemic spelling system, in a similar way as spelling in English. T. F. O'Rahilly expressed the opinion that Gaelic in the Isle of Man was saddled with an inadequate spelling which is neither traditional nor phonetic; if the traditional Gaelic orthography had been preserved, the close kinship that exists between Manx Gaelic and Scottish Gaelic would be obvious to all at first sight.
