Use italics to delineate foreign words that have not been adopted in English. Don't use any formatting or punctuation to delimit words that have been adopted in English.
- kung fu
- tuk tuk
If you're giving a translation of an English word, use the same format as for Foreign-language names. For example:
- The subway (French: Métro) is very convenient.
Alternately, you can use the foreign language word, and provide the English translation in parentheses but no italics afterwards, as in:
- The rathaus (city hall) is in the center of town.
If there's just no translation for a foreign word, or the word has been explained already, just use it without a translation.
