As mentioned above, vowels marked with the circumflex are always long, and those marked with the grave accent are always short. If a vowel is not marked with a diacritic, its length must be determined by its environment; the rules vary a bit according to dialect. In all dialects, only stressed vowels may be long; unstressed vowels are always short. An unmarked (stressed) vowel is long: • in the last syllable of a word when no consonant follows: (good). • before
voiced stops
b,
d,
g and before all
fricatives (except for
ll)
ch,
dd,
f,
ff,
th,
s: (son), (favourite), (thing), (night). An unmarked vowel is short: • in an unstressed (
proclitic) word: . • before
voiceless stops p,
t,
c (gate), (sheepfold) and before all
consonant clusters (except for those that start with s or ll) (saint), (hedge), (April). When preceding the final syllable in a multisyllabic word,
y is most often pronounced as : (whole) . In monosyllabic words, or in the final syllable of a word, it follows the same rules as other vowels: (day) (North) ~ (South), (island) (North) ~ (South). Before
l,
m,
n, and
r, unmarked vowels are long in some words and short in others: : (The last four examples are given in South Welsh pronunciation only since vowels in nonfinal syllables are always short in North Welsh.) Before
nn and
rr, vowels are always short: (ash trees), (to win), (stone). In Northern dialects, long vowels are stressed and appear in the final syllable of the word. Vowels in non-final syllables are always short. In addition to the rules above, a vowel is long in the North before a consonant cluster beginning with
s: (witness). Before
ll, a vowel is short when no consonant follows the
ll: (better) It is long when another consonant does follow the
ll: (hair). In Southern dialects, long vowels may appear in a stressed
penultimate syllable as well as in a stressed word-final syllable. Before
ll, a stressed vowel in the last syllable can be either long (e.g. "better" ) or short (e.g. "hole" ). However, a stressed vowel in the
penult before
ll is always short: (clothes). Before
s, a stressed vowel in the last syllable is long, as mentioned above, but a stressed vowel in the penult is short: (measure) . Vowels are always short before consonant clusters: (saint), (hair), (witness). == Digraphs ==
