In that case you would say "Ich habe drei Frauen" meaning "I have three wives" if you had them all at once. or if you said the german equivalent of "That is one of my wives" ( I believe "das ist eine meiner Frauen" in German")
By saying "Das ist meine dritte Frau" meaning "That is my third wife" it pretty much implies you have had two different marriages and two divorces before this third marriage.
Take it from me, I live in southern utah! And btw, Men don't usually introduce any of their wives as their third or first.
It could mean either. But you could be more specific, though it may sound awkward to be that specific.
Das ist meine dritte aktuelle Frau. -This is my third current wife. Das ist meine dritte Frau in meiner Frausfolge.-This is my third wife in my series of wives. (I'm not entirely sure if I'm right about Frausfolge, I based it off the german word for "series of kings" Königsfolge)
Thanks it is down to context again.
As jans43 said: The unisex hairdresser may say: "Das ist meine dritte Frau heute"
And a married man may say: ""Das ist meine dritte Ehefrau."
Whereas you can say "Frau" to your "Ehefrau"
Wish the green owl would give us hints or speak proper German or both.
No it wont be a normal sentence.. Islam doesnt allow you to marry whenever you like.. There are many conditions such as the will of the first wife.. Whether he is able to completely satisfy first wife in terms of her every need and/or any other wife he may have in future.. And many other conditions which pretty much dictates the multi-marriage obsolete in modern world.. Dont heed to stereotypes please
"Das" and "dies" are stand alone and do not have a noun. You can say: "Dies ist mein Freund" or "Das ist mein Freund" (This/That is my friend). When you introduce two people to a third person, you can say: "Dies ist Tom und das ist Anna" (This is Tom and that is Anna). Both are OK, but "Das" is the most common form.
You cannot say "das Hund ist schnell". It is grammatically wrong. You use dieser/diese/dieses instead. They have always a noun. You cannot use them without a noun. For example: "Dieser Hund ist schnell" (This dog is fast).
diese can translate as either this or as that and should be used in both your examples. (verbally pointing to something)
If you want to say something like "that's my wife you're talking about" then you use "die ist meine .." not das because wife is feminine.
"Das" as that is only used if referring to a neuter noun or to something which is not a noun eg "das weiß ich" = "I know that"
dieser/diese/dieses acts as an adjective. z.B. "Diese Frau ist meine Ehefrau." But in the sentence "Das ist meine Frau", the "das" acts as a noun.
You could say something like "Dies ist meine Frau", but I don't think this is as common (may not even be good Hochdeutsch). It's better to use "das" in the case where "this" or "that" is a noun: "Das ist meine Frau." = This/that is my wife. and only use dieser/diese/dieses (this) ... or jener/jene/jenes (that) as an adjective modifying a noun that follows it: "Diese/Jene Frau ist meine Ehefrau." = This/that woman is my wife.
