Advanced Features

Conjunct Consonant Formation

For Hindi and Marathi, you can create conjunct consonants using the '+' button:

2. Press '+' button: Button highlights, conjunct mode ON
3. Type second consonant: त (ta)
4. Result: क्त (kta) - conjunct formed automatically

Examples:

• क + [+] + र = क्र (kra) - as in "क्रम"
• स + [+] + त = स्त (sta) - as in "मस्त"
• न + [+] + य = न्य (nya) - as in "पुन्य"

Toggle Mode: Press '+' again to turn OFF conjunct mode if activated accidentally.
