Sentence under question:
大きな鳥{とり}が空{そら}を飛んでいます。
My question: "ookii" is an i-adjective, followed by a noun "tori". Why does the i-adj. in this sentence have a "na"?
What I found in "Tanoshii Japanese dictionary": "大{おお}きな noun or verb acting prenominally". Sorry, but at my present Japanese level I really can't grasp this explanation.
Could anyone please answer my question and maybe give me a good source with explanation? Thanks
