The Arwi alphabet is the Arabic alphabet, with thirteen additional letters used to represent the Tamil vowels
e and
o and several Tamil consonants that could not be mapped to Arabic sounds.
Vowels :
Notes • Unlike other vowels, and unlike in Persian, Urdu, or Arabic, when vowels
i, ī, e, ē come at the beginning of a word (respectively ), the vowel carrier is not
alif () but is instead
yeh (). This spelling indicates the loss of glottal stop in words which start with these vowels, and its replacement by a
palatal sound. In rare cases, these vowels have indeed been written with
alif as their base.
Consonants :
Notes • The letter , representing the sound , has been written with the Arabic letter in the beginning of word,
geminated, or in combination with other consonants. This letter has been written with the Arabic letter in between vowels. • The letter , representing the sound [~], has been written with the Arabic letter in the beginning of word,
geminated, or after a nasal consonant. This letter has been written with the Arabic letter in at the beginning of words and in between vowels. The Arabic letter also represents the Tamil letter , representing the sound and the Tamil letter representing the sound . • For when this letter is geminated, i.e. , some historic manuscripts used the letter
dal with two dots underneath, the modified Arwi letter . But most manuscripts simply used the letter
dal with one dot underneath, and with a
gemination diacritic, the letter . • The Arabic letter has not been used in a widespread manner for representing the Tamil letter (representing the sound ). Most historic sources use the letter for this Tamil letter as well as for the Tamil letter (representing the sound ). • For the Tamil letter , representing the sound [~], the Arabic letter is used. Except if this letter is in between vowels, or following a nasal sound, where the letter is used. • The Tamil letter representing the sound has usually been written with the Arabic letter . In addition, in rare occasions, this sound has been represented by the Arabic letter . This sound doesn't occur at beginning of words. == Sample Texts ==
