Nouns name things, whether they be concrete or abstract: from people, places, objects, qualities and ideas through to concepts and emotions. Welsh nouns are grouped into two categories according to ‘grammatical gender’ -masculine and feminine. This is not the same as sexual gender. It is just a method of classifying nouns, used in at least half the world’s languages, that regulates the behaviour of the associated words and thus controls grammar, pronunciation, spelling and syntax.

This list is, of course, not comprehensive; there are countless other nouns and I have had to be selective to keep this article within reasonable bounds. Many sub-lists of noun groups, such as animals, foods, plants, days, months, numbers etc, have either been excluded or greatly reduced; I aim to cover these specialist categories in future. For the full vocabulary of Cymraeg, there is nothing to match Y Geriadur Mawr, first published by Gwasg Gomer in 1958 and now onto its 23rd edition.

KEY
