Complete Cognates, Partial Cognates . Cognates arranged thematically: Adjectives | Animals | Birds | Clothes | Colours | Conjunctions | Countries | Directions | Food and Drink | Landscape | Buildings | Languages | Metals | Musical terms | Names | Numbers | Parts of the body | People | Prepositions | Pronouns | Sea creatures | Time expressions | Tools | Trees and Plants | Vehicles | Verbs | Weather | Other words
The Celtiadur blog is a collection of Celtic cognates, with definitions, pronunciation, etymologies - includes the modern Celtic languages, older versions of these languages, such as Middle Welsh, Middle Breton and Old Irish, and their extinct and reconstructed relatives and ancestors, including Gaulish, Proto-Brythonic and Proto-Celtic.
On the Celtic Pathways podcast I discuss connections between the Celtic languages, and look for words with Celtic roots in non-Celtic languages, such as English, French, Spanish, Galician and Portuguese.
Breton, Celtiberian, Cornish, Cumbric, Gaulish, Irish, Lepontic, Lusitanian, Manx, Scottish Gaelic, Welsh
