As mentioned, successive consonants lacking a vowel in between them may physically join as a 'conjunct'. The government of these clusters ranges from widely to narrowly applicable rules, with special exceptions within. While standardized for the most part, there are certain variations in clustering, of which the Unicode used on this page is just one scheme. The rules: • 23 out of the 36 consonants contain a vertical right stroke (ખ, ધ, ળ etc.). As first or middle fragments/members of a cluster, they lose that stroke. e.g. ત + વ = ત્વ, ણ + ઢ = ણ્ઢ, થ + થ = થ્થ. • શ
ś(a) appears as a different, simple ribbon-shaped fragment preceding વ
va, ન
na, ચ
ca and ર
ra. Thus શ્વ
śva, શ્ન
śna, શ્ચ
śca and શ્ર
śra. In the first three cases the second member appears to be squished down to accommodate શ's ribbon fragment. In શ્ચ
śca we see ચ's
Devanagari equivalent of च as the squished-down second member. See the note on ર to understand the formation of શ્ર
śra. • ર
r(a) • as a first member it takes the form of a curved upward dash above the final character or its
kāno. e.g. ર્ભ
rbha, ર્ભા
rbhā, ર્ગ્મ
rgma, ર્ગ્મા
rgmā. • as a final member • with છ
chha, ટ
ṭa, ઠ
ṭha, ડ
ḍa, ઢ
ḍha and દ
da, it is two lines below the character, pointed downwards and apart. Thus છ્ર, ટ્ર, ઠ્ર, ડ્ર, ઢ્ર and દ્ર. • elsewhere it is a diagonal stroke jutting leftwards and down. e.g. ક્ર, ગ્ર, ભ્ર. ત
ta is shifted up to make ત્ર
tra. And as said before, શ
ś(a) is modified to શ્ર
śra. • Vertical combination of
geminates
ṭṭa,
ṭhṭha,
ḍḍa and
ḍhḍha: ટ્ટ, ઠ્ઠ, ડ્ડ, ઢ્ઢ. Also, ટ્ઠ
ṭṭha and ડ્ઢ
ḍḍha. • As first shown with શ્ચ
śca, while Gujarati is a separate script with its own novel characters, for compounds it will often use the Devanagari versions. • દ
d(a) as द preceding ગ
ga, ઘ
gha, ધ
dha, બ
ba (as ब), ભ
bha, વ
va, મ
ma and ર
ra. The first six-second members are shrunken and hang at an angle off the bottom left corner of the preceding દ/द. Thus દ્ગ
dga, દ્ઘ
dgha, દ્ધ
ddha, દ્બ
dba, દ્ભ
dbha, દ્વ
dva, દ્મ
dma and દ્ર
dra. • હ
h(a) as ह preceding ન
na, મ
ma, ય
ya, ર
ra, વ
va and ઋ
ṛ. Thus હ્ન
hna, હ્મ
hma, હ્ય
hya, હ્ર
hra, હ્વ
hva and હૃ
hṛ. • when ઙ
ṅa and ઞ
ña are first members we get second members of ક
ka as क (only in certain fonts), ચ
ca as च and જ
ja as ज. ઙ forms compounds through vertical combination. ઞ's strokeless fragment connects to the stroke of the second member, jutting upwards while pushing the second member down. Thus ઙ્ક
ṅka, ઙ્ગ
ṅga, ઙ્ઘ
ṅgha, ઙ્ક્ષ
ṅkṣa, ઞ્ચ
ñca and ઞ્જ
ñja. • The remaining vertical stroke-less characters join by squeezing close together. e.g. ક્ય
kya, જ્જ
jja. • Outstanding special forms: ન્ન
nna, ત્ત
tta, દ્દ
dda and દ્ય
dya. The role and nature of
Sanskrit must be taken into consideration to understand the occurrence of consonant clusters. The
orthography of written Sanskrit was completely phonetic, and had a tradition of not separating words by spaces.
Morphologically it was highly
synthetic, and it had a great capacity to form large compound words. Thus clustering was highly frequent, and it is Sanskrit loanwords to the Gujarati language that are the grounds of most clusters. Gujarati, on the other hand, is more
analytic, has phonetically smaller, simpler words, and has a script whose orthography is slightly imperfect (
a-elision) and separates words by spaces. Thus evolved Gujarati words are less a cause for clusters. The same can be said of Gujarati's other longstanding source of words,
Persian, which also provides phonetically smaller and simpler words. An example attesting to this general theme is that of the series of
d- clusters. These are essentially Sanskrit clusters, using the original Devanagari forms. There are no cluster forms for formations such as
dta,
dka, etc. because such formations weren't permitted in
Sanskrit phonology anyway. They are permitted under
Gujarati phonology, but are written unclustered (પદત
padata "position", કૂદકો
kūdko "leap"), with patterns such as
a-elision at work instead. ==Romanization==
