Mozilla L10n Style Guide Bengali Bangladesh (bn-BD)


Style guides define the standard against which we determine a translation's quality. They contain rules that are both defined by Mozilla and by Mozilla's localization communities on how to best translate text in Mozilla products, websites, and other projects. Style guides are used to both translate and evaluate a translation's quality. By following these rules, a translator has a better chance of producing a high quality translation that represents Mozilla values and culture.

Available style guide for Bangla:

Bengali Language

Bengali also known by its endonym Bangla, is an Indo-Aryan language spoken in South Asia. It is the national and official language of the People's Republic of Bangladesh, and official language of several northeastern states of the Republic of India, including West Bengal, Tripura, Assam (Barak Valley) and Andaman and Nicobar Islands. more in Wikipedia


The Bengali alphabet or Bangla alphabet (Bengali: বাংলা লিপি Bangla lipi) is the writing system for the Bengali language and is the 6th most widely used writing system in the world. The script is shared by Assamese with minor variations and is the basis for the other writing systems like Meithei and Bishnupriya Manipuri. Historically, the script has also been used to write Sanskrit in the region of Bengal.

Language-specific Mozilla style

Formality and Tone

Instructions from the early days of Bengli l10n from Ankur Bangla Project read-more

While translating, remember not to kill the language ;-). Do not overdo the translation - do not use Sadhu Basha . Also, when the computer is addressing the user, it is samman-shuchak (karun, balun, etc) while the computer is addressed by karo, balo, etc. If a Bangla equivalent sounds too out of the ordinary - keep the English word (in Bangla script) - it can be always changed/improved later. DO NOT overdo anything.

The language should not be too much formal and bookish. The tone should be less formal and bookish.
The user should be addressed as "আপনি". Machine provide any message should be in "আপনি" tone.
In a case of command machine should be addressed machine as "তুমি".

Natural expression

Handling cultural references, idioms, and slang

Style consistency

Finally, adherence to Mozilla and third-party branding and style guides should be respected throughout a localization project. More information on Mozilla-specific branding rules can be found here. For example, some brand names should never be translated, such as "Firefox".

Abbreviation এ প্রতিটি অক্ষরকে আলাদাভাবে উচ্চারণ করা হয় এবং এটাকে শব্দ হিসেবে পড়া হয় না। কিন্তু Acronyms কে একটি শব্দ হিসেবে উচ্চারণ করা হয় এবং Abbreviation এর মত প্রতিটি অক্ষরকে আলাদাভাবে উচ্চারণ করা হয় না। যেমন SIM এর উচ্চারণ "এসআইএম" এর বদলে "সিম" করা হয়ে থাকে। এ ক্ষেত্রে আমরা শব্দকে উচ্চারণের ভিত্তিতে বাংলা করা যাবে যদি শব্দটি সমাজে বহুল প্রচলিত হয়ে থাকে।


Bengali punctuation marks, apart from the downstroke দাড়ি dari (|), the Bengali equivalent of a full stop, have been adopted from western scripts and their usage is similar: Commas, semicolons, colons, quotation marks, etc. are the same as in English. Capital letters are absent in the Bengali script so proper names are unmarked.
