Clarification on Compound Japanese nouns


I've sort of thought of making sentences for words in my custom Anki deck to
sort of improve my sentence writing skills.

Now, the word is 矛盾{むじゅん}, which means "contradiction"

The sentence I've come up with is:

あなたは歩くの矛盾んだよ (You are a walking contradiction.)

Was my translation of "walking contradiction" correct?

I kind of feel that 歩き矛盾 or 歩く矛盾 works too, although I'm not that sure. The
latter seems somewhat correct as a noun phrase, but the former somehow sounds
more...natural(?), although I'm not sure since it seems more like a compound
word I just invented, so it feels kind of wrong too. Please correct me on
this.

Also if there is a more direct Japanese translation to the phrase, please
tell.




Correct one: 歩く矛盾 (Verb in 連体形 + noun. No idea what 連体形 is called in English)

"歩くの矛盾" could colloquially mean "the fact that you walk is a contradiction",
but in this case you should preferably say "歩くのが矛盾" or "歩くのは矛盾", i.e. with は
or が, and as always they have slightly different meanings, but I'm gonna skip
the explanation since it's outside the focus of your question.

If you keep saying "歩き矛盾", you might at some point succeed in making Japanese
people believe that such an expression exists, because there's in principle
nothing wrong about it. But in the current state it's difficult to make them
understand what you exactly want to say.

And finally, あなたは歩く矛盾だよ is not only a great translation, but also sounds so
perfectly natural that it's hard to believe that it was originally created by
a Japanese-learner.
