Wiktionary:Frequency lists/Welsh/Top 500

These frequency lists are based on work conducted by Ellis, N. C., O'Dochartaigh, C., Hicks, W., Morgan, M., & Laporte, N. (2001). The list comprises of an analysis of 1,079,032 words of written, everyday Welsh. It is based on 500 samples of approximately 2000 words each, selected from a representative range of text types to illustrate modern (mainly post 1970) Welsh writing.

The sample included materials from the fields of novels and short stories, religious writing, children's literature (both factual and fiction), non-fiction materials in the fields of education, science, business, leisure activities, etc., public lectures, newspapers and magazines, both national and local, reminiscences, academic writing, and general administrative materials (letters, reports, minutes of meetings).

The resultant corpus was analysed to produce frequency counts of words both in their raw form and as counts of lemmas where each token is demutated and tagged to its root. This analysis also derives basic information concerning the frequencies of different word classes, inflections, mutations, and other grammatical features.
