Answer

Tamil Bible in English letters: what Tanglish is and how to read scripture with it

Who Tanglish reading is for

Most Tamil families outside Tamil Nadu have someone who understands every word of a Tamil sermon but cannot follow the printed Bible. Children who grew up in Singapore, Malaysia, the Gulf, Europe or North America; adults who went to English-medium schools; spouses who learned Tamil by ear. They already know the language. What they lack is the script, and Tanglish removes that one barrier.

How the app produces Tanglish

The app does not carry a second, romanised copy of the Bible. It converts the Tamil text on your phone, verse by verse, as you read. The conversion follows the everyday spelling Tamil speakers use when texting, not the academic ISO 15919 system with its diacritics, because that is the spelling people already read fluently.

A few conventions make it read naturally:

• th is த (thevan, God), zh is ழ (thaazhchi), ng is ங, nj is ஞ.
• Long vowels are doubled letters: aa, ee, oo (vaanam, jeevan).
• A single consonant after a vowel is written soft, the way it is spoken: magan, anbu, indha. Doubled and word-initial consonants stay hard: pakkam, appam. Clusters are written the way people text them: karthar, velicham, Yesu.
• A word-final ஏ becomes ae: Mosae, engae.

Three ways to read a chapter

At the top of every chapter there is a switch with three positions:

1. Tamil — the original script only.
2. Tanglish — English letters only.
3. Both — each verse in Tamil with its Tanglish line directly beneath. Reading this way for a few weeks is the easiest route to learning the script, because you always know what the Tamil letters are saying.

The choice is remembered. The app also asks on first launch whether you want Tamil or Tanglish as your main mode, and a toggle on the home screen switches between them any time. In Tanglish mode the verse of the day, its WhatsApp share card, search results and saved verses all appear in Tanglish, and the tabs and book names switch to English so the whole app is navigable without Tamil script.

What Tanglish is not

Tanglish is a change of letters, not a translation. The words are still the Tamil Old Version, word for word; only the alphabet changes. You still need to understand spoken Tamil to follow it. It is also generated by rules, so an occasional word may be spelled slightly differently from how you would type it yourself — the meaning is never affected.
