Oh well, cardinals and ordinals are more or less the same.
We do have some other languages on our side:
Well, you are exactly right! As someone who used to speak Polish as the second language
(as a child, not anymore, actually, largely superseded by German and Italian, countries,
where I've spent 6 and 4 years, respectively), I should have thought better! Of course, in
Polish IT IS indeed "mniej o więcej", and I should have realised the difference!
I've studied SOME Hebrew and even much less Turkish some 45 years ago, but was never
any good at any of those, and which are NOT Indo-European anyway, so they do not count.
But I WAS rather serious with Farsi, and used it on many occasions, and it is obviously as
closely related to Russian and German, as you can imagine, so I have to think and consult
my Iranian friends.
Lithuanian, that's what makes me slightly alarmed. It is BY FAR the most archaic of all
Indo-European languages (it still preserves the dual number, alongside with singular and plural,
both in the nominal and verbal systems, separate masculine and feminine verbal forms IN
PLURAL for PAST tenses, etc., etc., etc.) This suggests that Lithuanian forms might be THE
most ancient ones.
