How to contribute to the community by translating WordPress

I’ve been general translations editors for the Bulgarian language in the local WordPress community for years, yet I decided to write this article in English, as I believe the approach here could be followed for just any other language.


In order to contribute to WordPress through translating the project in another language, you should:

  • have solid knowledge in English and the language you are translating to. Needless to say, otherwise you could be dealing more harm than actually helping the community.
  • have an active account in, as you’ll need it for working in and Local communities might have other slack addresses using that account too.
  • bring a laptop with yourself at the event you are attending or have one at home if you are contributing remotely.
  • know that you don’t need to be a programmer or be extremely experienced in WordPress in order to be helpful. Having that knowledge could be of use to you, but is definitelly not required.

Before you actually start translating:

There are a few resources you should get aquainted with, before you dive into the work you are preparing for:

  1. Local language translation guidelines – each language with an active translating community should have such a source of documentation. For Bulgarian it’s located here:превод-на-български. If you can’t find such for your language of choice, contact folks in the #polyglots channel in and ask them about it directly. Or even better, contact the local community, if listed in this page:
    Translating without getting to know these guidelines could lead to bad translations and lack of consistency between your translations and those already done by other translators.
  2. Locale glossary – usually it’s located in GlotPress under the main local page. Here’s the one for Bulgarian: . It’s the place where most common terms are listed with their translation for sake of consistency. Always check the glossary if you are unsure of what could be the best translation for a technical term.
    If you haven’t translated WordPress before, it’s a must-read.
  3. Polyglots handbook – this is the general handbook for translations in WordPress:
    It’s a pretty extensive material, so feel free to skip it if you feel confident enough or if you are too eager to already start translating.
  4. Project-specific glossaries – if you are translating a specific plugin or theme, it’s good idea to check whether there is a glossary for the terms used in that project. Here’s an example with a glossary specifically for WooCommerce in Bulgarian:
  5. GlotPress – it’s the software that is hosted on, the main translations portal for the WordPress community. You can start your contribution here.

How it actually works?

Strings of all WordPress projects are available for translation in, where anyone with an active account can contribute by suggesting translations to a specific language. The suggestions by all translators are then being reviewed by translation editors who could be global for the given language (GTE), or responsible for that specific project (PTE).

Start from picking a project that you’d like to contribute to:

Core always comes first!

Usually WordPress Core (button WordPress) from the list is the highest priority. From that list always focus on the current and future versions of the project, unless you want to edit a specific old string which is not translated well. There are separate projects for each major WordPress version, but no projects for the minor ones, as they don’t bring too many new strings.

Themes & Plugins buttons are self-explanatory, Meta is meant for internal projects as,, support forums, plugins and themes directories and a few others. Apps is used for two mobile applications, used by the SaaS, owned by Automattic (which is odd), and an Android app for WordCamps.

If you have difficulty deciding on the plugins or themes that it’s worth working on, have a look a the Stats divide in plugins and themes groups, where you’ll see the list of the most popular ones with info on how much work is left there.

Once you’ve chosen a project to work on, you might have to decide on the subproject. WordPress Core has a few sub projects, related to the context:

WordPress Core sub projects

Plugins have different ones – development and stable, depending whether you’d be translating the latest string from “trunk” of the SVN repository (development) or the latest release of the plugin (stable). These two sub projects are divided further into strings from the project and strings from the readme.txt file, which is being displayed in the Plugin Directory.

A plugin translations sub projects

As translations from Development are directly being applied to the Stable release, whenever they match, you should always prefer the Development sub projects, when translating a project.

There are a number of fields one can use for filtering the strings for adding a translation or editing existing ones. See the image below:

Filters for translatable strings

Searching for strings, containing a specific word is done by using the “Term” field. The rest of the options there are self-explanatory.

Above the search and filter form there is a number of statuses for direct filtering of all strings for the project. When you are starting your contribution efforts best is to focus on the Untranslated list. “Fuzzy” are suggestions that were once valid, but after changes in the strings from the code are in a state of uncertainty and need to be checked in order to ensure no bad translations are entering the project. “Warning” translations are such that have mismatched punctuation, placeholders, HTML tags, spacing or other issues, that are automatically detected. Some of them could easily be fixed, so feel free to go through them, if you find any. “Waiting” are the strings that someone already have a proposed translation. This doesn’t mean that you can’t suggest a better one.

While translating, GlotPress provides you a number of tools you can use for doing a better job with your contribution. See the image below:

Goodies in GlotPress when translating a string
  1. Code references display the source of the string. If you have even the most basic understanding of PHP code, you will be able to gain additional context on the string that you are translating by checking the line in the code where this string is available.
  2. The button clones the original string in the text field for translation. Helpful when you are translating a string with special characters and HTML – typing them again could lead to typos.
  3. The help button provides some links to resources and explanation for the different statuses a translation might have.
  4. Suggestions, listed in this section, are taken from the consistency search (see it in the “useful tools” section). These come quite handy sometimes, but you should be careful to not apply blindly translations that are from a different context.
  5. In some rare occasions seeing the translation of the string in another language could help for making the right decision for your language.

Have in mind that if your translations get edited, even for just a typo or missing punctuation, they will no longer be accounted as your translations.

Useful tools during translation:

  • Google Translate – it’s the obvious one, but it’s important to remember, that it’s often far from perfect and the translation might totally miss the context of what you are translating. Still, it remains the best tool for getting a rough draft of a long paragraph that you could later edit and make more human-readable.
  • Glosbe Dictionary – extremely useful dictionary that searches terms in existing translations of documents, software and so on in order to provide the best options for the word or phrase you are looking for. I’ve had quite a few cases when this was more useful than Google Translate.
  • POEdit – it’s a desktop translation files editor that you can use in case you are offline or prefer not to work in the browser.
  • Consistency search – GlotPress provides a nice tool for searching a string in existing translations for the given locale within Bear in mind that not all translations are following the guidelines and and not all are relevant for your context.
  • Poopy Life – if you need a quick live test of a plugin or theme in order to see where a string is being displayed, this site will spin up a clean new WordPress instance in a minute and will remain for 24 hours. This is the perfect solution for anyone who doesn’t have a site of their own, nor a local testing environment. This could be used in combination with WP Reset and WP Rollback plugins in order to get a clean db after doing some tests or getting an older version of a plugin or theme.
