Tamil Subscripted Sanskrit Phonetic (OPTITRANS)

Description

Tamil Subscripted Sanskrit Phonetic (OPTITRANS) keyboard is Tamil-subscripted Sanskrit input method by a modified version of OPTITRANS and Harvard-Kyoto transliteration systems (see tamil_subscripted.toml).

You can use all the standard ITRANS key sequences plus key sequences such as the below.

nk->ங்க், nkh->ங்க்₂, ng->ங்க்₃, ngh->ங்க்₄ nch->ஞ்ச், nCh->ஞ்ச்₂, nc->ஞ்ச், nC->ஞ்ச்₂, nchh->ஞ்ச்₂, nj->ஞ்ஜ், njh->ஞ்ஜ்₂, nT->ண்ட், nTh->ண்ட்₂, nD->ண்ட்₃, nDh->ண்ட்₄ c->ச், C->ச்₂, z->ஃ₂ஜ், S->ஷ், jn->ஜ்ஞ், R->ரு₂

Examples: Type saMskRta for ஸம்₂ஸ்க்ரு₂த.

• The motivation behind some basic additions made to the basic ITRANS scheme is described here, along with a tabulated comparison with several other transliteration schemes.

Consonants

The following table shows the English letters to type to get Tamil consonants. e.g. type k for க், ka for க, R for ரு₂, RR for ரூ₂, LLi for லு₂, etc.

Vowels and Vowel Signs

In the following table, vowels on their own and vowels combined with the consonant 'k' are shown in OPTITRANS transliteration scheme on the top two rows. The third row shows Tamil vowels. The fourth row shows the vowel combined with the consonant 'k'. 'ka' needs no special key sequence, as the vowel 'a' is simply typed after the consonant.

Aspirated and voiced consonants (kha, gha and the like) carry subscript numerals that move to the end of the akshara when vowels are added: e.g. g e produces கெ₃.

The following table shows consonants again, each with the inherent vowel a.

Perso-Arabic and other loans

Nukta (़) letters for Perso-Arabic loans, plus the Tamil-specific ற், are typed with a leading .. A few also have a bare key. As elsewhere, the forms below are halanta (add a vowel key for the signed form).

Consonantal Diacritics

Arranged with the vowels are two consonantal diacritics, the final nasal anusvāra ம்₂ M and the final fricative visarga ஃ H (called அம்₂ aṃ and அஃ aḥ). Another diacritic used in transcribing other languages is the candrabindu/anunāsika ம்₃ .N (அம்₃). These consonantal diacritics follow the vowel signs including the implicit `a`. The following table shows consonant `k` followed by various vowels and the consonantal diacritics ம்₂ and ஃ.

Conjuncts

Consonant clusters are automatically formed, e.g. k t produces க்த்.

Explicit pulli

To force an explicit pulli at end of word, use .h e.g. k t .h space produces க்த்த் .

Punctuation

Numbers

1. Press the number keys to type Tamil digits. for example 9 produces ௯.
2. For typing the Arabic digits, press the number keys and then the backspace key, for example 9 Back space produces 9.
