まだほかにもある what is the subject in this sentence?


I understand this sentence means "there should be other things." But I just
can't wrap my head into its structure. If I parse the sentence like:

  1. ほか ＋ にも, I can't explain the に here.

  2. ほかに ＋ も, then the sentence is missing the subject because ほかに (in addition) is adverb.

Please show me how to parse the structure of this sentence. Thank you!




まだほかにもある doesn't contain a subject in it; まだ is an adverb, and ほかにも is an
adverbial phrase.

ほかにも consists of noun ほか + case particle に + adverbial/binding particle も.

ほか is a noun, and ほかに is an adverbial phrase, "in addition" or "other than
that". も is another particle adding the meaning "also" or "still". For the
noun ほか to be a subject, you need to say ほかが/ほかは/ほかも, not ほかに/ほかにも/ほかには.

eg

> ほかにもまだ仕事があります。← 仕事 is the subject.  
>  "There still is work, other than that." → "We have more work to do."
>
> これで全部ですか？ -- いいえ。まだほかにもあります。 ← The subject is not mentioned.  
>  "Is that all?" -- "No. There still is, other than that." → "We still have
> more [something unmentioned]."
