DuckFiasco:In response to Vestitor's post on the first page, some make conlangs for the same reason people make paintings that few will see or songs that no one will hear. It's another form of creativity and exploration.

It was the same for me, when I started making conlangs 20 years ago, and still from time to time I enjoy experimenting.

@Zvoc47

Concerning your original question, Esperanto has no copyright. You don't have to ask anyone in order to use it as a base for a proper conlang.

Bemused:...the vast majority of written English uses the Latin alphabet which has only five letters to represent vowels.

The Latin or Roman alphabet is the correct term. Not specifically the alphabet used for writing Latin.

And turn off caps lock.

Maybe he wanted to emphasize that minuscules and the long j, the round u and the double-u are later inventions.

Here's my alphabet.
All letters are pronounced as they would be in Croatian except if there's an extra explanation.
Each of these letters or double letters or triple letters or quadruple letters are one sound unless they merge like "w" or "y".

a
b
c = Esperanto and Croatian "c"
cx = Esperanto "cx" / Croatian "č"
d
dx = English "th" as in "that". Won't be used, but only for compatibility with English words
dj = Croatian "đ"
e
f
g
h
i
j = Esperanto "gx" / Croatian "dž"
k
l
lqx = "l" as a vowel as in "cuddle", "humble", "bundle". See "qx"
lx = Croatian "lj"
lxqx = See "qx"
m
mqx = See "qx"
n
nqx = See "qx"
nx = Croatian "nj"
nxqx = See "qx"
o
p
q = Regular "k", but for decoration like "Marqiz"
qx = Sounds like "uhh"/"err"/"ah". If after "l", "lx", "m", "n", "nx" or "r", it transforms that consonant into a vowel. For example, "castle" would be phonetized as "kaslqx" because the "l" sounds like a vowel
r = Croatian "r" and not English "r"
rqx = See "qx"
sx = Esperanto "sx" / Croatian "š"
t
tx = English "th" as in "health". Won't be used, but only for compatibility with English words
u
v
w = Romanji "w". Like a "u" merged with another vowel
x = Only if not after c, d, l, n, q, s, t. Sounds like "ks" as in "explozia"
y = Esperanto and Croatian "j" / Romanji "y"
z
zx = Esperanto "jx" / Croatian "ž"

I'm trying to see if I should reject this "qx" because I have a total mess with "lxqx" and "nxqx". It looks like a programming language (lol). But sometimes, some words contain a consonant as a vowel.
I might make these multilettered letters into diacritics. I was thinking of these.

cx=č
dx=ď
dj=đ
lqx=lø
lx=ł
lxqx=łø
nqx=nø
nx=ň
nxqx=ňø
qx=ø
rqx=rø
sx=š
tx=ť
zx=ž

The reason why I want diacritics is because they look fancy and save a lot of writing, but the reason why I don't want diacritics is because of the keyboard problem. No keyboard would support that. With my Croatian keyboard, I can only type čćžšđ.

While I think your language is a worthy project that will be a lot of fun, the English forum of an Esperanto website is probably not the best place to discuss the details of it as you work on it.

I would suggest either one of the Esperanto forums (maybe "pri cxio alia" or "pri aliaj lingvoj" ), or else Unilang, which is for more general language discussion.

lernu's website is for discussions in Esperanto on any topic (in the Esperanto forums) or on Esperanto in other language (in the national language forums), but there's not really a place for extensive discussions of a new conlang project in English.

Exactly. As was italic (16th century or so, I believe).

However, it misses the point that in the context of today, there isn't "the" Latin alphabet, but rather a family of Latin alphabets, many of which feature different letter sets. As a result, people refer to the English alphabet when they want to refer to only the set of glyphs "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" and not any of "ĄA̧ƁÇĐƊƉĘȨƏ̧Ɛ̧ƑĦĮI̧ƗƗ̧ƘŁƝǪO̧ØƠƆ̧ɌŞŢŦŲU̧ƯɄY̨Ƴąa̧ɓçđɗɖęȩə̧ɛ̧ƒħɦįi̧ɨɨ̧ƙłɲǫo̧øơɔ̧ɍşţŧųu̧ưʉy̨ƴ

Whew. Now, all those glyphs are part of somebody's "Latin" alphabet. But they aren't part of the "English" alphabet. (Except when stealing foreign words...)

So, in context of the original post. ENGLISH ALPHABET.

It's the other way around.

You did what to your knee? Are you over snapped?
