There is an undetermined number of languages in the Pokémon world(s) of the Suocéverse.

For the most part and for releases current to up to 2023, the subject of languages is mostly transparent with most dialogue taking place in English, Spanish or otherwise the OOU language of the publication. The exception is some showcases of in-universe languages that are usually provided with a translation, such as the speech of Reshiram and Zekrom in .

By and large it is assumed that every Human speaker speaks either a common / universal language such as Esperanto or Ido, or their in-universe native tongues; translation is glossed over unless explicitly shown otherwise.

For worldbuilding notes on human languages check Human Languages (pending).

As for Pokémon, they are assumed to speak or otherwise communicate in Monese, an umbrella term for a number of very closely related languages specific to Pokémon. Some Pokémon cultures also have more specific dialects or languages, though they are for the most part presumed to be (mostly) transparently translated when Pokémon speak to each other.

For worldbuilding notes on Monese and related languages and dialects check Monese Languages (pending).

The following is a list of pages tagged as “Language”:

• Lapine is used in stories featuring Nidoran species such as Silly Human, Romance is for Nidoran~ .
• Dranoskh is used in stories featuring select draconic species of Legendary tier, such as Tastes Anew .
• Thu'um is used in the names of members of some draconic societies in the La Plancha Ísparus Claim and the Dragon Paradise.

When IRL languages or stand-ins for those are used in dialogue or in in-universe rendering such as signs, they are marked where possible so that visual reading and screenreaders can recognize it.

In the primary release sites such as PC and AO3 that support semantic markup, such dialogue is marked with a HTML lang tag or an alternative. In narration, it is also usually described explicitly (eg.: “[Character] said in Portuguese”).

Preferred methods for adding such markup are:

• Marking with HTML lang attribute.
• (Alternatively) Marking with a semantic element that can be added to the markup (eg.: CSS classnames).
• Using an alternative semantic element such as tooltips.

When Pokémon language is used, in the primary release sites such as PC or AO3 that support semantic markup, such dialogue is marked and also a visual indication is provided that the language is not “human language”. The three general mechanisms for marking language used this way are:

• Marking with HTML lang attribute or a similar element.
• Styling with a different HTML Font family.
• Styling with a light / semitransparent background color or underline color.

In the primary sites and others that support it, “live” translation for dialogue sections is provided via Ruby (annotation) / Furigana for semantic translation. For sites that don't provide such support, a campaign is ongoing to request semantic support; and in the meanwhile non-semantic translation is provided either:

• inline-level tags that can imitate Okurigana , such as superscript / subscript.
• block-level tags that can be added at the end of the paragraph and provide or imitate a HTML Definition List or a HTML Aside.

In progress.

For semantic annotation of Human Languages, the lang tag is used via ISO 639-1 and ISO 639-3 language codes (2-codes and 3-codes, respectively). The list of in-universe codes for Suocéverse languages can be found at List of Language Codes.

For semantic annotation of Monese Languages, the lang tag is used via the ISO 639-2 extension for artificial languages: these take values of the form art-x-langname.

This table shows the interlanguage support of publication platforms as of Apr 2023, and the strategy used in rendering for them:

Platform	Ruby?	Aside?	Strategy / Alternatives
PokéCommunity	Y	Partial	PC CSS (eg.: [css-span]) for inline annotations. Pending revision for the engine's migration to Xenforo.
AO3	Y	Y	ISO639-2 markup. The VeniaSilente work skin provides classes for inline annotations.
Thousand Roads	N	Partial	Site suggests it supports <dl>, sup/sub but renderer doesn't; block-level asides are used for annotation.
Fanficslandia	N	Partial	Site suggests it supports protected classes but renderer doesn't; inline-level asides are used for annotation.
Canalave Library	N	Partial	Block-level asides are used for annotation.
Serebii Forums	N	N	Block-level asides are used for annotation.
Any generalistic BBCode forum	N	N	Block-level asides are used for annotation.
FF.net	N	N	Ignored for releases.
