> "Antienne" is regular and pronounced the same way all other -tienne words are as far as I know (like, say, Étienne). There is nothing regular here, since most dictionaries have no other common noun with the same ending. For instance the famous Littré only has "antienne" and "laurentienne", the latter with a "s" pronunciation. As for the rare words ending in "-tien" (and "-tienne" for feminine adjectives), roughly half of them are pronounced "t" and the others "s". E.g. "chrétien", "tien" (and derivatives like "entretien", "maintien"), against "béotien", "capétien", "égyptien". So, in French, in the words "chrétienne" and "égyptienne", the "t" is pronounced "t" only with the former word, even if both words have their origin in Greek through Latin.
