Translate using informal language by default i.e. as if you are writing a Tweet.

Some languages (e.g. French, Spanish, German) have some levels of formality based on the audience (politeness). If the source sentence contains a level of formality please try to carry over the formality/politeness level from source to target language. If the source sentence does not provide a level of formality (e.g. English) please translate with an informal style by default.

Polite/Formal language can be used only in cases where it is more appropriate for the given source sentence in the specific context.

Do not use the level of formality which would be unnatural in the context of the sentence. For example, use informal language for vulgar or offensive contents.

• I love your ass → translate it in an informal way, for example “deinen” instead of “Ihren” in German

• Exception: In some languages, formal is the more accepted form, e.g. Japanese, in that case, go with the more accepted form of language.

• If using ‘polite’ words is not common or expected, it’s fine to omit them. e.g. “please”.
