I am clear when to use the above and the correct suffixes when you have compound nouns eg tomato soup ,straight possession ie John's book or if the sentence contains the word of.
If I see an English sentence such as HOW MUCH FRENCH DO YOU KNOW [UNDERSTAND ]?.Then I am completely lost when the Turkish is given as FRANSCIANINI NE KADARSINE BILYIORSUN
I AM NOT WORRIED ABOUT THE QUESTION OR VERB ENDING
WHERE I AM CONFUSED IS WHY THE FIRST TWO WORDS HAVE THESE POSSESSIVE ENDINGS AND THE FACT NE KADAR IS A VERB OF QUANTITY AND NOT A NOUN
Can anyone explain ,please ?

Thank you for your reply
The full sample sentence that gives me trouble is
Fransizcanin ne kardinini hatirliyorsun
What gives me my general problem over this is that possessive endings are given in text books etc as two nouns together eg John's book ,car keys ,the garden gate .
But in the sample sentence the first word is a noun but the second an adverb of quantity
In short, why are possessive suffixes added to a noun followed by an adverb when i cannot see any possession ?
Thanks for your help
John

Further to my last post,I have come across the following in-COLLOQUIAL TURKISH BY Y. MARDIN [SIMILAR TO OTHER TEXT BOOKS]
"POSSESSIVE RELATIONSHIP -EXPLANATION -The relationship between two or more nouns,or a pronoun and one or more nouns ,involves a special construction in Turkish. "
No mention of adverbs eg ne kadar which has given rise to my difficulty

Thank you for your help CALIPTRIX AND VS
As i said i am quite happy when two nouns are together although in my elementary state i may get the suffixes sometimes wrong
What i am really after is a full explanation why an adverb or any other part of speech after a noun takes the possessive
Thank you vs as at least the examples you gave teaches me that ne kadar following a noun takes the possive
Any other help on this point would be much appreciated
