A suite of convenient and useful Welsh-English dictionaries

Cysgeir is a comprehensive collection of useful dictionaries for your computer and forms part of the Cysgliad package. It contains general every-day words as well as specialized terminology taken from the terminology dictionaries developed at Bangor University over the years.

Advantages of an Electronic Dictionary

As an electronic set of dictionaries, Cysgeir has numerous advantages over traditional paper dictionaries. With Cysgeir, finding a word is quick and easy – start typing the word that you’re looking for and the dictionary will start looking for it even before you’ve finished typing. If you’re unsure of the exact spelling, just typing in the first few letters will narrow down the possible words so that you can select the appropriate word from the search window on the left.

Searching in either language

You can search from Welsh to English or from English to Welsh, and changing the search direction is as easy as clicking a single button. The interface language can also be changed so that the program menus and options appear in English rather than Welsh.

Special Features:


The dictionary also has several useful features which traditional dictionaries lack. For example, Cysgeir can demutate a word. Type in gath and Cysgeir will recognize the word as a form of cath (cat) and take you to the appropriate dictionary entry.

Deconjugate verbs and prepositions

Similarly, Cysgeir can deconjugate rhedodd (he/she ran) and take you to the dictionary entry for rhedeg (to run).

Rhyming Dictionary

Cysgeir also possesses the ability to function as a Welsh rhyming dictionary. Simply type ‘*’ before the letters of the rhyme and the search will return all words that correspond to the same rhyme.

Finding Terms

Another of Cysgeir’s advantages is that it can quickly identify multi-word terms or phrases that contain your search word; click on Cysgeir’s blue button and these will be displayed. If you search for the word pysgod (fish) for example, clicking on the blue button will display all the terms and phrases that include pysgod, for instance gwerthwr pysgod (fishmonger) and pysgodyn sgyfeiniog (lungfish).
