As I'd noted before, there's a lot here 😢 Sooo, it'll be after the cut! Things reviewed here:
vowels
silent E
/s/
/k/ (+ /ke/)
/θ/
Letter: Y
LL
Z
CH
We'll start simply with the vowels!
A = /a/ or "ah"
E/Ē = /ɛ/ or "eh"
I = /ɪ/ or "igh"
Ì = /i/ or "ee"
O = /o/ or "oh"
U = /ɤ/ or "uh"
Ú = /u/ or "ooh"
Buuuuut we also have silent E's. To be silent, the E cannot have the accent, and the I and U cannot have the accent either.
Silent E's make the vowel preceding them "say their name". So A becomes /æ/, E becomes /i/, I becomes /ai/, O remains /o/, and U becomes /iu/. The E is not pronounced. Examples: lú calrete (/sal-reet/, meaning a secret), iplire (/igh-plai-er/, meaning "to be"), múnuce (/moo-n-igh-ooh-s/, meaning "please").
If the I or U do have an accent over them, the E, even without an accent, is pronounced as described above. Example: lú llunìte (/yuh-knee-teh/, meaning a unit or type of something).
Now for /s/. There are two (technically maybe three?) letters that can make this sound:
C: before a consonant, U, Ú, A, or E. Example: le cadwìn (/sad-ween/, meaning a division or separation).
S: before I, Ì, O, or at the end of a word. Example: lú sizìence (/sih-zee-en-say/, meaning science as a whole).
(technically) Z. Example: lú zúlē (/soo-lay/, meaning the sun).
Aaand /k/. There's C and K for this, but also QUE.
C: before I, Ì, O, or the end of a word. Examples: le cinulú (/kin-uh-loo/, meaning an ocean) and le cimsilì (/kim-th-igh-lee/, meaning curiosity).
K: whenever.
QUE: whenever (but most frequently at the end of a word). The UE is not pronounced (don't ask why they're there. okay, fine: it's some fucky thing they stole from Old Eviclon in the early 1100s). Examples: lú billaque (/bih-yah-k/, meaning a book) and vúnique (/voo-nick/, meaning the number five).
(On the topic of QUE: QUĒ is /kɛ/ or "kay".)
/θ/ ("th")! This can be both S and TH.
S: before U, Ú, A, E, or a consonant. Example: Ansúla (/ah-n-thoo-lah/, the Common name for the Turakurtz-aligned god).
TH: happens I, Ì, O, or at the end of a word. Examples: thìa (/th-ee-ah/, meaning the number three) and multhìr (/mull-th-ear/, meaning to die).
The letter Y can mean two things:
/j/ when before a consonant. Example: lú tryvel (/tr-yuh-veh-l/, meaning a travel).
/wi/ when before a vowel or at the end of a word. Examples: y (/wee/, meaning "yes"), Tallabúy (/tal-ah-boo-wee/, the Common name for the Transportau-aligned god), and lú fumúyē (/fuh-moo-wee-eh/, the word for the Transportau's floaters).
LL: /l/ for everything EXCEPT:
The beginning of a word. Example: lú lleano (/yeh-ahn-oh/, meaning an island).
Before I. Example: le llingor (/yin-gor/, meaning a seed for planting).
After I. Example: lú billaque.
In which case, as seen, LL becomes /j/.
Z can be either /z/ or /ʃ/. There aren't really rules for these, unfortunately; you sorta gotta figure it out, lol. Most will be /z/, though. Exceptions include: lú zaús (/sh-ow-s/, meaning the direction South) and lú zìf (/she-f/, meaning a form or shape).
CH = /tʃ/. For example: chonger (/ch-awh-n-gur/, meaning "to change")
uhhh, that's all I can think of! soo: hope this was interesting!! :)
