Welcome to Gweiadur!

Gweiadur - a project to create a collection of multimedia resources for users of Welsh of all ages.

Gweiadur Pawb - the core of the project. Based on over 30 years of dictionary building, it includes:

  • 400,000 Welsh words (including mutations and verb forms)
  • 38,000 Welsh definitions and phrases
  • verbs conjugated in every tense
  • adjectives compared
  • prepositions conjugated
  • gramatical advice about word usage
  • the mutations which are triggered by certain words
  • audio pronunciation
  • corresponding English words at sense level
  • English/Welsh index

As the project progresses, we will update and extend Gweiadur Pawb, e.g. with country and place names, Welsh thesaurus, English thesaurus, etc.

We will also add other specialist resources to Gweiadur, e.g. for children and learners.
