Older versions of the alphabet
Before the standardisation of the Maltese alphabet, there were several ways of writing the sounds peculiar to Maltese, namely ⟨ċ⟩, ⟨ġ⟩, ⟨għ⟩, ⟨ħ⟩, ⟨w⟩, ⟨x⟩, and ⟨ż⟩.
/t͡ʃ/ was formerly written as ⟨c⟩ (in front of ⟨e⟩ and ⟨i⟩, in Italian fashion). Vella used ⟨ ç ⟩ for /t͡ʃ/. ⟨ç⟩ was used in other books during the 19th century. Rather than using a c with a cedilla, ⟨ç⟩, Panzavecchia used a c with ogonek ⟨c̨⟩. A Short Grammar of the Maltese Language used ⟨ch⟩ for /t͡ʃ/, in English fashion. It was not until 1866 that ⟨ċ⟩ came to be used.
/d͡ʒ/ and /g/, now written with ⟨ġ⟩ and ⟨g⟩ respectively, were formerly confused. When they were differentiated, /g/ was written as ⟨gk⟩, ⟨g⟩, ⟨gh⟩ and (by Vassalli) as a mirrored Arabic/Syriac gimel resembling a sideways V. On the other hand, /d͡ʒ/ was more commonly written as ⟨g⟩ or ⟨j⟩ in English fashion. Vella used a ⟨g⟩ with diaeresis, ⟨g̈⟩, but in 1843 reduced it to one dot, instituting the modern ⟨ġ⟩.
Until the middle of the 19th century, two sounds which would merge into /ˤː/ were differentiated in Maltese. These were variously represented as ⟨gh⟩, ⟨ġh⟩, ⟨gh´⟩, ⟨gh˙⟩ and with two letters not represented in Unicode (they resembled an upside down U). Panzavecchia used a specially designed font with a curly ⟨gh⟩. A Short Grammar of the Maltese Language used ⟨a⟩ with a superscript Arabic ʿayn (⟨ع⟩) to represent /ˤː/. ⟨għ⟩ itself was first used in Nuova guida alla conversazione italiana, inglese e maltese.
The letter ⟨ħ⟩ had the most variations before being standardised in 1866. It was variously written as ⟨ch⟩, and as a ⟨h⟩ with various diacritics or curly modifications. Some of these symbols were used for [ ħ ] and some for [ x ]. None of these are present in Unicode. ⟨ħ⟩ was first used in 1900, although the capital ⟨Ħ⟩ was used earlier (in 1845), where its lower case counterpart was a dotted h.
/w/ was written as ⟨w⟩, ⟨u⟩ or as a modified u (not present in Unicode).
The sounds /ʃ/, /ʒ/ (now represented with ⟨x⟩) were traditionally written as ⟨sc⟩ or ⟨x⟩. Vassalli invented a special character similar to ⟨ Ɯ ⟩, just wider, and Panzavecchia used an ⟨sc⟩ ligature to represent /ʃ/ and /ʒ/, in the Italian fashion.
/t͡s/ and /d͡z/ (now represented with ⟨z⟩) were formerly confused with, /z/ (now represented with ⟨ż⟩). When they were differentiated, /t͡s/ and /d͡z/ were written as ⟨ts⟩, ⟨z⟩, ⟨ ʒ ⟩ or even ⟨ż⟩. On the other hand, /z/ was written as ⟨ż⟩, ⟨ds⟩, ⟨ts⟩, ⟨ʒ⟩ and ⟨z⟩.
Prior to 1900, /k/ was written as ⟨k⟩, as well as ⟨c⟩, ⟨ch⟩ and ⟨q⟩ (in words derived from Italian and Latin).
Vassalli's 1796 work contained several new letters to represent the sounds of the Maltese language, which included the invention of several ad-hoc letters as well as the importation of Cyrillic ge, che, sha, and ze. His alphabet is set out in full with modern-day equivalents where known:
A, a = a
B, b = b
T, t = t
D, d = d
E, e = e
F, f = f
[V, or a Syriac/Arabic gimel open to the right] = g
[Ч], ɥ = ċ
H, h = h
ȣ
Ө, ө
Y, y = j
Г = ġ
З, з
U = ħ
I, i = i
J, j = j
K, k = k
[I with a small c superimposed on it]
L, l = l
M, m = m
N, n = n
O, o = o
P, p = p
R, r = r
S, s = s
Ɯ, ɯ = x
V, v = v
U, u = u
W, w = w
Z, z = z
Ʒ, ʒ = ż
Æ, æ = final e
Five grave accented vowels are also used to indicate which syllable should be stressed: Àà, Èè, Ìì, Òò, and Ùù.
