This is a maintenance category, used for maintenance of the Wikipedia project. It is not part of the encyclopedia and contains non-article pages, or groups articles by status rather than subject. Do not include this category in content categories. This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. They are not part of the encyclopedia's categorization scheme. This category is hidden on its member pages—unless the corresponding user preference (Appearance → Show hidden categories) is set. These categories can be used to track, build and organize lists of pages needing "attention en masse" (for example, pages using deprecated syntax), or that may need to be edited at someone's earliest convenience. These categories also serve to aggregate members of several lists or sub-categories into a larger, more efficient list (discriminated by classifications). Administrators: Please do not delete this category even if it is empty! This category may be empty occasionally or even most of the time.

This category is used to track {{Lang}}, {{Langx}}, and {{Lang-??}} template errors and other Module:Lang-related errors. This category is used only by Module:Lang.

See List of ISO 639 language codes for many modern languages: List of ISO 639-3 codes lists all the 3-letter codes.

Module:Lang consolidates the processing of {{Lang}} and {{Langx}} templates. As part of that, the module emits error messages when the template parameters are used inappropriately or when the data assigned to the parameters is malformed. The error messages have the form:

[<text>] <error message> (help link)

where <text> is the text supplied to the template and rendered without proper html markup. Error messages are defined here:

The text has italic markup error commonly occurs for these reasons:

1. text includes text written with more than one alphabet

   in this example, Ancient Greek with a Latin script transliteration (also called Romanization)

   {{Langx|grc|Ἀθῆναι, ''Athênai''}}

   the above should be rewritten

   {{Langx|grc|Ἀθῆναι|translit=Athênai}} → Ancient Greek: Ἀθῆναι, romanized: Athênai

   A similar condition may exist for languages that have multiple writing systems, where the second is not a transliteration of the first but the actual text as written in the 'other' writing system. For such templates, consider writing:

   {{Lang-xx|<first text>|italic=<yes|no>|rtl=<yes|no>}} {{Lang|xx|<second text>}}

2. text includes italic markup to override default italic markup set by the {{Lang-xx}} template (see the settings box in the template doc §Usage section)

   {{Langx|sco|''Dumbairton''}} – 'Dumbairton' is a proper name so should not be italicized

   the above should be rewritten

   {{Langx|sco|Dumbairton|italic=no}} → Scots: Dumbairton

   for languages like Kurdish that use more than one script and where the template default is to italicize

   {{Lang-ku|هه‌ڵپه‌ركێ}} – text holds a script that should not be italicized

   the above should be rewritten:

   {{Langx|ku|هه‌ڵپه‌ركێ|italic=no|rtl=yes}} → Kurdish: هه‌ڵپه‌ركێ

   (it is prudent to set |rtl= to yes or no so that the template includes the correct html markup in the rendering)

   when text holds Latin transliterations of right-to-left languages like Arabic (no Arabic script), consider setting |script=Latn so that the template removes the default right-to-left html markup from the rendering and automatically renders in italics:

   {{Langx|ar|''min sallaf es-sabt lāqā el-ḥadd qiddāmūh''}}

   the above could be rewritten:

   {{Langx|ar|min sallaf es-sabt lāqā el-ḥadd qiddāmūh|script=Latn}} → [min sallaf es-sabt lāqā el-ḥadd qiddāmūh] Error: {{Langx}}: invalid parameter: |script= (help)

   but, consider using the perhaps more semantically correct {{transl}} instead:

   [[Romanization of Arabic|Arabic]]: {{transl|ar|min sallaf es-sabt lāqā el-ḥadd qiddāmūh}} → Arabic: min sallaf es-sabt lāqā el-ḥadd qiddāmūh

3. text includes italic wiki markup to 'turn off' italics for an inserted English-language conjunction between two non-English words or phrases:

   in this example, an English-language conjunction, 'or', is inserted between two Lithuanian phrases; English is not Lithuanian so does not belong inside of the {{Langx|lt}} template:

   {{Langx|lt|Rusijos lietuvių seimas Petrograde'' or ''Visos Rusijos lietuvių seimas}}

   the above should be rewritten:

   {{Langx|lt|Rusijos lietuvių seimas Petrograde}} or {{Lang|lt|Visos Rusijos lietuvių seimas}} → Lithuanian: Rusijos lietuvių seimas Petrograde or Visos Rusijos lietuvių seimas

4. When the template is {{Langx|en}} or {{Lang|en}}, consider removing the template; this is the English Wikipedia, it is not usually necessary to identify English text in the English Wikipedia as being English.
5. Sometimes the inclusion of italic markup is just wrong.

   For example, Cyrillic script is generally not to be rendered in italic font; see MOS:FOREIGNITALIC.

   {{Langx|uk|''Українська Народна Міліція''}}

   the above should be rewritten:

   {{Langx|uk|Українська Народна Міліція}} → Ukrainian: Українська Народна Міліція
