Languages

Most characters seem to speak a common language. Given that only Qum and children seem to speak it improperly, it is apparently well-known by most groups and nations. However, other languages do exist. There have been examples of untranslated elven and dwarven words, marked in the text with a different color. Sierra has stated that the same colors will hold for conversations entirely in other languages.

Elven
Text in the Elven language is marked in. You first encounter it when the party comes across a pair of elves in Delgar Forrest.

Known words and expressions:
 * : used for greetings and farewells; it means something like "it is peaceful" (the meaning is debated by Simon and Aka).
 * : the elven name for the elven language.
 * : exclamation uttered by one of the elves after spotting Altina among humans, in human gear. It might be a generic expression of (unpleasant?) surprise, but the elf calls her an "apostate" in the very next sentence, so the meaning of the expression might be related to the accusation.

It's unclear whether the names of the elf kingdoms Darghelon and Gheldaron and the elf-queened Ghenalon have any significance other than the common suffix.

Dwarven
Text in the Dwarven language is marked in. You first encounter it in Eustrin. It has a Germanic vibe.

Known words and expressions:
 * : "Yes", the same as in German.
 * : "Dwarves"; the singular is unclear.
 * : a greeting.

Other
You can encounter a text that Yarra claims to be written in "ancient Succubus". She's able to read some of it.
