Which one is correct? 私が好きだ日本の食べ物はてんぷらです。 Or 私が好きな日本の食べ物はてんぷらです。

I am not sure whether to use sukina or sukida Please post your answer with explaination. Thank you.

Answer 1

好きな

It's being used attributively, to modify "Japanese food". 好きだ is used predicatively.　だ is the copula, so 好きだ almost always occurs at the end of a sentence. It cannot be used before nouns to modify them.
