Vowels
The vowels in Quenya are pronounced distinctly in all positions. The difference between long and short vowels lies mainly in the length, not the quality, of the sound. Long vowels are marked with an acute accent.
á = long “aaaah”, as in “father”
a = short “ah”, as the a in “aisle” (just a shorter version of the “ah” sound in “father”)
é = long “e”, as in German “Mehr” (no exact equivalent in English, but something between “ee” and “eh”)
e = short “eh”, as in “end”
í = long “ee”, as in “machine” (or “see”)
i = short “i”, as in “pit”
ó = long “oooh”, as in “sore”
o = short “o”, as in “box”
ú = long “uuuh”, as in “brute” (or “room”)
u = short “u”, as in “put”
A diphthong is a combination of vowels that represent a single sound. There are 6 diphtongs in Quenya: ai (as in “aisle”), au (“house”), eu (British “so”), iu (“yule”), oi (“oil”), ui (“ruin”). Vowels in all other combinations are to be pronounced separately. This, as well as final e, is often marked by dieresis (two dots). The use of dieresis is optional, and it is not used in Tengwar writing.
Consonants
c = always pronounced as “k” (“come”)
h = pronounced as “h” (hand) in the beginning of words, and as “ch” (German “Bach”) between consonants. Not pronounced at all in the combinations hw, hy, hl, hr in the beginning of words.
l = always like in “let”
ng = both sounds are heard, as in “finger”, not as in “singer”
r = trilled, as in Spanish, Italian, Russian and Scottish English. Not as in French.
s = always unvoiced as in “so”
y = always a consonant, pronounced like in “yes”
qu = “kw”: the “u” in this combination does not count as a vowel; it is just another way to spell the “w” sound
A combination of consecutive consonants is called a consonant cluster.
