Overview

This keyboard is designed for the Tamil language. It is a phonetic keyboard, which means the Tamil characters are arranged according to the letters of the English keyboard. This makes it easy to use for people learning Tamil, as well as Tamil speakers. Typing follows a consonant-vowel pattern, and the keyboard is designed for use with a normal QWERTY (English) keyboard.

Most computers will automatically download a special font if needed to display this language correctly.

Using this Keyboard

Keyboard Layout

Quickstart

This keyboard makes typing in Tamil straightforward for anyone familiar with a normal English keyboard. Consonants and vowels are arranged on the keyboard so that pressing an English letter displays the Tamil character which sounds closest to that letter. Some characters, however, representing sounds which do not exist in the English alphabet, are located on unused keys. Grantha consonants are also on the keyboard, and long vowels are typed by pressing the vowel key twice, or by pressing [S*]and the vowel key. For example, the vowel is typed by pressing i, while pressing ii or I produces the long vowel .

Most of the characters used in Tamil are combinations of consonants and vowels, and these do not appear on the keyboard. Combined consonant-vowel characters are entered by typing the consonant, then the vowel. To enter சா, which is a combination of ச் and , type s then A, and the combinant character will automatically be displayed. Pressing Backspace once will delete only the vowel component, so the character displayed on the screen will change back to ச், and change again if a different vowel is typed.

Keyboard Details

This keyboard uses a consonant-vowel order for text input, so the consonant character is always typed before the vowel, regardless of where (relative to the consonant) the vowel marker symbol appears. As syllables are typed, the characters entered are automatically converted to the appropriate consonant-vowel combinant. While only the combinant characters are displayed on screen, the consonant and vowel are both stored, so that pressing Backspace once after a combinant deletes only the vowel component. This means it is necessary to press Backspace twice to delete a combinant character. However, pressing the Delete key with the cursor in front of a combinant character removes the whole character with one keystroke.

The visible keyboard layout consists of the ten vowels அ ஆ இ ஈ உ ஊ எ ஏ ஒ ஓ (the vowels ஐ ஔ are typed with two keystrokes), the eighteen consonants க ங ச ஞ ட ண த ந ப ம ய ர ல வ ழ ள ற ன, the Grantha consonants ஸ ஜ ஹ க்ஷ ( is typed with two keystrokes, and ஸ்ரீ with three) and the Aytham mark.

Consonants and Pulli Marks

Most of the consonants are arranged so that they can be typed with a single key. A few consonants which use the same English (Roman) letter as another consonant, or which have no equivalent English letter, must be typed with two keystrokes. See the complete keyboard chart for details.

This keyboard does not have a key for the Pulli mark , which defines a standalone consonant. Instead, every consonant will display the Pulli mark when it is typed, and the Pulli mark will disappear when a vowel is typed. The implicit vowel thus needs to be typed, though it is not actually displayed when combined with a consonant.

The SRii Character

There are two ways of entering this character: Sri or Shri. Currently, some browsers support one, both or neither of these entry methods. Click here if you are having difficulty entering this character.

Vowels

Vowels are typed using the English vowel letters. Tamil distinguishes between short and long vowel sounds, and the keyboard is arranged so that pressing any vowel key once will produce the short vowel, while pressing it twice, or pressing [S*]together with the vowel key, will produce the long vowel. When typing, it is often more efficient to press the vowel key twice rather than using [S*]. The vowels and , which do not have equivalent single letters in English, are typed with two keystrokes as shown below.

Keystroke Examples

The following table gives specific examples of how to input characters based on the consonant . The Grantha consonants use the same input method. Examples of these with the consonant are also given below.

Typing Conventions

Aside from the alternate methods of typing long vowels described above, several other conventions are incorporated in this keyboard. These are not 'rules' which must be followed, rather they are shortcuts, or ways of increasing the efficiency of typing Tamil using English (Roman) letters. These conventions may not actually reduce the number of keystrokes needed for typing characters, but by largely avoiding [S*]combinations, they make typing Tamil easier and faster.

ற் Consonant
The consonant ற் is usually typed with R, while typing a lower-case r produces ர். Because ற் sometimes appears twice in succession, the keyboard has been arranged so that pressing dr or tr produces ற்ற், without needing to use [S*].
Similarly, because ற் never appears after ன், pressing dr or tr after ன் produces ன்ற், again avoiding the use of [S*].
ன் and ந் Consonants
The consonant ன் is usually typed by pressing n, and ந் is produced by typing w or n-. However, if n is pressed after a space or a carriage return, it will produce ந்.
ட், ன் and ண் Consonants
Typing d (ட்) after ன் will change the ன் to ண் (otherwise typed with N). ட் can also be entered by pressing t, but this will not change the ன் character.
ஞ் Consonant
This character can be entered either by typing W or nj. When ஞ் is followed by ச் which is often typed with ch (though s is an alternate way of typing this character), the sequence njj will produce ஞ்ச்.
த் Consonant
This character can be typed using either T or th. In some words, this character is repeated twice in succession. Typing tth provides a shortcut to entering this.
English words used in Tamil
Some English words that can be written in Tamil script will not display correctly if typed exactly as they are written, as the keyboard automatically makes some of the changes listed above. To avoid this, it may be necessary to insert spaces when typing and delete these spaces afterwards.

Other Characters

This keyboard does not contain characters such as the symbols for day, month, year, etc., or the glyphs used as vowel modifiers. Some of the alternate Tamil keyboards do allow these characters to be typed.

Troubleshooting

Using Tamil keyboards with Word 2007

Sometimes when using Word 2007, the Pulli mark ் is not suppressed correctly. For example:

Key sequenceCorrect outputWord output
க + அ + கககக்க
க + க + க+ க க்கக்க க்க்க்க

The easiest ways to deal with this are to move the cursor and press Backspace to delete the unwanted Pulli mark, or else enable the Text Services Framework Add-In if you are using Keyman Desktop Professional. Disabling Tamil language editing in Microsoft Office Language Settings will also correct the input behaviour, but this is not recommended, as it makes selection of fonts more difficult.

Fonts

This keyboard allows only the standard Tamil characters, so will work with the fonts supplied with Windows. No further downloads of fonts should be required.

If the characters you type or those on the On Screen Keyboard do not appear to display correctly, please read the KeymanWeb troubleshooting guide.

Problem Solving

If the preceding consonant does not change to a vowel-consonant combinant character when you type a vowel, confirm that you have not typed the first vowel அ, which identifies the consonant as the implicit-vowel consonant, or a space. Typing either of these after a consonant will prevent that consonant from changing to a combinant character.
