## GPC Geiriadur Welsh Dictionary Description
[English below]
Mae ap GPC yn cynnwys holl ddata Geiriadur Prifysgol Cymru, geiriadur Cymraeg cynhwysfawr tebyg i’r Oxford English Dictionary. Yn wahanol i GPC Ar Lein (gpc.cymru), mae modd lawrlwytho holl gynnwys y Geiriadur i’ch dyfais fel nad oes angen cysylltiad â’r Rhyngrwyd i’w ddefnyddio. Diffinnir pob gair yn Gymraeg gyda chyfystyron Saesneg ac enghreifftiau o’i ddefnydd o bob cyfnod ynghyd â tharddiad (etymoleg) i bob gair. Rhoddir gwybodaeth ramadegol fel cenedl a ffurfiau lluosog enwau.

Nodweddion:
Geiriadur Prifysgol Cymru yw’r geiriadur Cymraeg mwyaf gyda 
- 124,500 o ddangoseiriau 
- 7,150 o amrywiadau 
- 34,400 o gyfuniadau (ymadroddion) 
- 475,000 o ddyfyniadau enghreifftiol gyda manylion am y ffynonellau 
- dros 60,000 o groesgyfeiriadau.
Mae modd chwilio drwy’r dangoseiriau, yr amrywiadau, a’r cyfuniadau am air neu ymadrodd. 
Er mwyn hwyluso’r chwilio, mae’r ap yn anwybyddu acenion, rhifau, a’r sillgoll, gan restru’r holl ganlyniadau i chi gael dewis o’u plith.
Os yw’r ap yn methu dod o hyd i’r gair rydych wedi chwilio amdano, bydd yn cynnig rhestr o eiriau tebyg.
Mae’r ap yn chwilio am ffurfiau treigledig geiriau yn awtomatig er mwyn dod o hyd i fwy o ganlyniadau.
Gallwch ddefnyddio nodau arbennig (neu ‘wildcards’:  ‘*’, ‘?’, ‘+’).
Gallwch chwilio drwy’r cyfystyron Saesneg gan ddefnyddio’r un nodau arbennig.
Does dim angen bod ar lein i ddefnyddio’r ap. Mae’n bosibl lawrlwytho’r holl ddata (tua 185MB) drwy gysylltiad WiFi er mwyn gallu defnyddio’r ap yn annibynnol o’r Rhyngrwyd. Os nad oes digon o le ar y ddyfais, mae’n bosibl lawrlwytho fersiwn llai o’r data (sy’n cymryd tua 132MB drwy hepgor y dyfyniadau enghreifftiol).
Mae’r ap yn cynnwys dwy gêm eiriau syml - anagramau a geiriau coll - gan ddefnyddio diffiniadau’r Geiriadur fel cliwiau. Mae’n bosibl cyfyngu’r dewis o eiriau i’ch chwiliadau diweddar - yn arbennig o ddefnyddiol i ddysgwyr er mwyn ymarfer geirfa newydd.
Ceir adran ‘Cymorth’ i ateb cwestiynau cyffredin ac i roi rhagor o wybodaeth.
Datblygwyd gyda chymorth ariannol Llywodraeth Cymru. 

======== ENGLISH =========

Geiriadur Prifysgol Cymru: A Dictionary of the Welsh Language is the Welsh-language equivalent of the Oxford English Dictionary. In contrast with GPC Online (gpc.wales), you can download the entire contents of the Dictionary to your device so it can be used offline. Every word is defined in Welsh with English synonyms and illustrative quotations, together with the word’s etymology, and grammatical information such as the gender and plurals of nouns.

Features:
Geiriadur Prifysgol Cymru is the largest Welsh dictionary with 
- 124,500 headwords
 - 7,150 variant forms 
- 34,400 collocations (phrases) 
- 475,000 illustrative quotations with source references 
- over 60,000 cross-references
The headwords, variant forms, and collocations are searchable by word or phrase. Accents, numerals, and apostrophes are ignored to simplify input - instead all matches are listed for you to choose from.
Fuzzy searching: If the app fails to find the word you are searching for it will suggest similar words.
The app searches automatically for mutated forms in order to find additional results.
You can use wildcards (‘*’, ‘?’, ‘+’).
You can search the English synonyms, using the same wildcards.
You can use the app online, with no data downloaded. Alternatively you can download all the data (about 185MB) via WiFi and use it offline. If you don’t have enough room on your device, you can download the data without the quotations (which takes about 132MB). 
The app contains two simple word games - an anagram game and a hidden-word game - with clues based on the definitions in the Dictionary. The selection of words can be confined to your recent searches - particularly useful for learners to practice new vocabulary.
There is a ‘Help’ section to answer frequently asked questions and to supply further information. 
Developed with the financial assistance of the Welsh Government.

Diolch am ddiweddariad 1.1 ... braf i gael yr ap yn gweithio eto :-)
-- Inventory Counter, 2020-11-05

### *---- "Compatibility problem"
Roughly since I last updated iOS, I can no longer tap to open entries when I search for a word, rendering the app unusable - this is a shame as I generally use this app a great deal, as Welsh philology is one of my favourite hobbies/compulsions! I&#039;ll be happy to provide a much higher review when this is fixed.

Diweddariad iOS14 yn golygu na allwch glicio ar air.

### *---- "Illogical app"
As a learner of Welsh, I was looking for a good dictionary to use. This app seems to have no logic to the way it operates when I can get it to work. It constantly has an error report of ‘no external connection’. A completely useless to me
-- Sgs663, 2018-02-11

Licio bod GPC yn app o&#039;r diwedd, ond un feirniadaeth fach, mae&#039;n andros o araf sy&#039;n difetha&#039;r peth fymryn, ond fel arall ma&#039;n wych!

Ap da iawn, ond mae angen tipyn bach o newidiadau. Diolch!
