Welsh language research focuses on the study of the Welsh language, a Celtic language spoken in Wales and in pockets in England and Argentina. Research in this area can include studies on the history, phonetics, grammar, syntax, semantics, sociolinguistics, language acquisition, and language revitalization efforts of the Welsh language. Researchers may also explore the cultural and literary aspects of the Welsh language, as well as its interaction with English and other languages. Studies in this area aim to enhance our understanding of the Welsh language and contribute to its preservation and promotion.
