Welsh morphology is the study of the internal structure of the words of the Welsh language and their systematic relationship within the language. This includes the principles by which Welsh words and morphemes arise, their form and derivation. A fundamental aspect of this study is the analysis of its inflectional system, and how this encodes grammatical categories.[1][2][3]
The historical development of the Welsh language has followed an atypical pattern resulting in two highly divergent registers: a literary form, and a colloquial form. These forms are both in modern use, with literary Welsh used in only the most formal or traditional artistic or religious contexts. The morphology of the two registers is so different that even native speakers of Welsh may need specific education in literary Welsh; this goes beyond that which is usually needed by native speakers of most other languages, when they encounter the most formal or rarefied register of their mother tongue.[4]
The morphology of the two registers is discussed in separate articles:
