Documentation / Translating
Some things should never be translated: the name of your business, your products, places. SwiftLing has two ways to say so.
Words that are never translated
On Settings › Translation service, under Words that are never translated, add a word or a name such as Villa Marija. When a service translates, it keeps it as you wrote it, in every language. You can still change it by hand in the editor.
Words are matched as whole words with their letters as written: Lavanda is kept, lavanda in a sentence is translated.
Content that is never translated
On Settings › General › Content types, set a kind of content to Never. Visitors see the original in every language. It is left out of the Translations lists, the editor and the counts.
A single page
In the editor, choose Keep the original under How this page shows in a language. See The editor.
