Here's a famously romantic poster showing
Yr Wyddor (the alphabet) neatly illustrated around a '
bardic' (
en,
cym), or '
druidic' (
en,
cym) theme, including many of
Iolo Morganwg's (
en,
cym) famous inventions, such as the
nod cyfrin (
en cym) and
'coelbren y beirdd' (
en,
cym).
Underneath the poster I've given the names of the letters in Welsh.

Here are the names of the letters in Welsh
The pronunciations are given
in Welsh, since it is to all intents and purposes a phonetic alphabet (or a WYSIWYG!) - and in any case, in what other language could they be!?. For guidelines, see the
Pronunciation discussion.
The first three are "a", "bi" and "èc", which are pronunced like the (British) English 'are', 'bee', 'eck'. (The symbol "è" represents a short vowel sound; all other vowels are long)
A a;
B bi;
C èc;
Ch èch;
D di;
Dd èdd;
E e;
F èf;
Ff èff;
G èg;
Ng èng;
H aits;
I i dot;
J je;
L èl;
Ll èll;

N èn;
O o;
P pi;
Ph phi;
R èr;
Rh rhi;
S ès;
T ti;
Th èth;
U u bedol;
W w;

This list includes "j" which is absent from the poster for various intriguing reasons.
