Let's break out your individual German words:
Guten, Tag, wo, wohnen, du, ich, bin, sechzehn, Jahre, alt, meine, Liebchen, Mutter, Vater, Grossmutter, Grossvater, (Numbers up to 100)
That's sixteen words plus the numbers. Let's see,
ein - neun and
zehn - hundert, that makes nineteen more and 35 words gives you a 3. Perhaps my scale is too generous at the low end but I didn't want to make it too difficult to use.
You probably don't know what
wiedersehen means (again-see), nor
auf, so I didn't give you credit for them.
I think you're trying to say
Ich liebe dich, "I love you." Your sentence would translate as "I am you," but the grammar is incorrect.
Shizer (and various other rude words)
I'm not giving you credit for that one because you spelled it wrong and if that's the way you pronounce it you're also saying it wrong. I don't recommend learning profanity when you know hardly anything else of a language, so I'm not going to teach you how to say it right.
Perhaps a 3/4 then if you count numbers?
It's a power-of-three scale. Zero = one word, 1 = three words, 2 = ten words.... 10 = one hundred thousand words. 3/4 would mean you know two words and you know many more than that.
All the phrases I know in Russian (transliterated of course): Da, Niet, Niet Dorma
Do you mean
nye doma, not at home? There's no R in it. Unless you speak a non-rhotic (silent R) British dialect and throw the R in to make it look like an AW sound. That's not the standard way of transliterating Russian.
That's a ZH, not a J. The ZH in "Asian," "collision," and many French words like
jour and
garage. It's customarily transliterated as "pozhaluysta" because that's the way it's spelled in Russian. But Russian spelling is not perfectly phonetic: the unaccented O is pronounced as an "uh" and the Y is silent. Sometimes it's written "pozhalu'sta" in Roman letters, to get it half right.
Apart from my 6 in French, I know nothing of any other languages. Pretty shaming really.
6 = one thousand words. That's nothing to be ashamed of. Very few Americans know a thousand words in any foreign language.
