5 Common Mistakes When Subtitling in Sinhala (and How to Avoid Them)

Written by Srisubs Editorial

Introduction

Creating subtitles is an art form. Unlike translating a written book or news article, subtitle translators must convey emotion, tone, and character personality within strict timing and character constraints.

When subtitling English media into Sinhala, translators frequently encounter unique linguistic challenges. Here are the 5 most common mistakes in Sinhala subtitling and how you can fix them.

1. Using Formal Written Sinhala (ලිඛිත සිංහල) Instead of Spoken Sinhala (කථික සිංහල)

The biggest pitfall in Sinhala subtitling is applying the grammar and verb endings of formal written Sinhala to casual cinema dialogue.

The Problem: Written Sinhala uses formal verb endings like **-න්නේය, -න්නීය, -න්නාහ, -ති**. In a modern thriller, comedy, or drama, characters talk casually. Using literary Sinhala makes young or casual characters sound like a 19th-century history textbook.

Examples: - **English**: *"Hey, what are you doing here?"* - ❌ **Formal Literary**: `ඔබ මෙහි කුමක් කරන්නේද?` - ✅ **Natural Spoken**: `හේයි, ඔයා මොකද මෙහෙ කරන්නේ?`

  • **English**: *"I told you not to go there!"*
  • ❌ **Formal Literary**: `මම ඔබට එහි නොයන ලෙස පැවසුවෙමි!`
  • ✅ **Natural Spoken**: `මම ඔයාට කිව්වනේ එහෙ යන්න එපා කියලා!`

2. Translating Idioms and Slang Word-for-Word

Idioms carry figurative meaning that cannot be directly translated word-for-word without confusing the audience.

Examples: - **English**: *"It's a piece of cake!"* - ❌ **Literal**: `ඒක කේක් කෑල්ලක්!` (Nonsensical in Sinhala) - ✅ **Natural Translation**: `ඒක ලේසි වැඩක්!` or `ඒක සුළු දෙයක්!`

  • **English**: *"Break a leg tonight!"*
  • ❌ **Literal**: `අද රෑ කකුලක් කඩාගන්න!`
  • ✅ **Natural Translation**: `අද හොඳට කරන්න! සුබ පැතුම්!`

3. Exceeding Reading Speed Limits (Characters Per Second)

Viewers need time to read the text and watch the actor's facial expressions simultaneously.

Best Practice Rules: - **Max Lines**: Keep subtitles to a maximum of **2 lines per cue**. - **Line Length**: Aim for under **35 to 40 characters per line**. - **Duration**: A 2-line subtitle should remain on screen for at least **2.5 to 3.0 seconds**, while very short 1-word cues should stay for at least **1.2 seconds**.

If an English sentence is very fast and wordy, condense the phrasing in Sinhala rather than attempting to translate every single filler word.

4. Breaking Sentences at Awkward Grammatical Points

When a long dialogue sentence spans multiple subtitle cues, never split closely linked grammatical units (noun phrases or compound verbs).

❌ Bad Split: ```text 1 00:01:10,000 --> 00:01:12,500 අපි හෙට උදෙන්ම කොළඹ

2 00:01:12,600 --> 00:01:15,000 යන්න ඕනේ කියලා තාත්තා කිව්වා. ```

✅ Better Natural Split: ```text 1 00:01:10,000 --> 00:01:12,500 තාත්තා කිව්වා අපි හෙට උදෙන්ම,

2 00:01:12,600 --> 00:01:15,000 කොළඹ යන්න ඕනේ කියලා. ```

5. Overlooking Sinhala Unicode Diacritic Placement

Sinhala uses complex Unicode combining marks (කොම්බුව, ඇලපිල්ල, ඉස්පිල්ල, පාපිල්ල). Older subtitling software or non-Unicode fonts (like legacy FM-fonts) frequently produce broken glyphs where vowel signs detach from their base consonants.

How to Prevent This: 1. Always author and export subtitles in **UTF-8 encoding**. 2. Use modern Unicode fonts designed for digital screens, such as **Noto Sans Sinhala** or **Iskoola Pota**. 3. Verify that zero-width joiners (`ZWJ`, `U+200D`) used for rendering `ර්‍` (රේඵය) and `්‍ය` (යංසය) are preserved properly by your subtitle editor.

Summary

Great Sinhala subtitles feel effortless to read. By prioritizing **natural spoken phrasing**, **respecting reading speed limits**, and **maintaining proper UTF-8 font standards**, your subtitle translations will captivate viewers from start to finish!
