I was reading the Evening Prayers in the 1950's OCA prayerbook, and came across where it mentions "our purest Sovereign-Lady Theotokos" (Prechistaya Vladychitsa nasha Bogoroditsa).
I will point out that it does not refer to her merely as "Our Lady", but as "Our purest
", having two more words.
Yet it was remarkable to me that it did use a word that can be vaguely approximated in meaning with the aristocratic Russian word "Dama" (in English: Lady). The word that it uses is "Vladychitsa". This is the female form of the word "Vladyka", which you may recognize as what we call our Bishops (in English: "Master"). The OCA book writes "Vladychitsa" in English as "Sovereign-Lady", which is more than just an aristocratic lady ("Dama").
As for the term Vladychitsa,
when it is used in isolation, as in "Our Lady", it appears to generally have a Catholic connotation in Russian, and one comes across this usage rarely.
I did find a speech where Catherine the Great, in concluding peace with the Turks in 1793, uses it this way: "Our Vladychitsa in the vengeance of her works celebrates brightly!"
Catherine the Great was Orthodox, but it is worth pointing out that she had come from Germany and converted to Orthodoxy. I think she may have had inexactness in Russian, because I read that she wrote the common word "еще" as "ис че", which by the way is how it sounds. And who is going to correct the Empress on grammar points?
One website uses the title "nasha Vladychitsa"
in amongst many other titles, instead of using it as the main title in isolation (ie. "...our lady and..."
instead of "Our Lady of"
). But this website doesn't seem to be a very "formal" Orthodox one, to say the least. Its right-hand side panel takes the idea of literary "bullet-points" to a whole new level. The quote is: "She is our Lady, the most Holy, Humble, Most merciful, our Vladychitsa and Patroness of the Christian people, and not the self-called Masonic puppets."
The other two websites I found have Vladychitsa as a Catholic term:
