+1 As a native Cantonese speaker, I often talk like this. e.g. I sometimes say something like 那套餐根本吃不飽 whereas saying 那套餐根本不夠吃 would have been the correct sentence. It seems like intrinsically, Chinese users allow for such ambiguity in our speech, which I just realized. But of course, it may just be me that speaks like this.

Please let me point out a small mistake in your analysis: 那本书 is the *theme*, and it's the *object* of the whole sentence (it's what is being searched). What is missing is the *subject* (who performs the search) *before* the verb 找

@TangHo allow me to insist. the *subject* of a sentence is what does or is something. In case of a transitive verb as 找, it's the agent. In this sentence 那本书 is not an agent. It's the *theme*, whereas 我/他/大卫 is the actual agent of the search.

Ok, I understand what you're saying. I suggest to change this sentence *(It sounds like the subject is 那本书. All it needs is an object after the verb 找到 to make it true)* to *In this example, it sounds like the subject is 那本书)*. The second part looks confusing to me

@TangHo I'm not too familiar with this aspect in Chinese grammar though. Going through the Hong Kong education system, I've been told that omitting the subject in a sentences other than imperative forms a grammatically wrong sentence 病句. Do you have any sources on whether doing such is acceptable, (in prescriptive grammar in the edu. system)? I'm quite curious. Because this answer does seem a bit hand-wavy.

@TangHo I see. Never mind then. I was seriously interested if you know if there are sources/guidelines for educators saying in Standard Chinese, subjects must not be omitted in sentences except for imperatives. (I can't find any official documents.) I was told leaving subjects out creates 病句, which would be mistakes in an exam and marks are deducted. As a native speaker, I find omitting subjects completely acceptable in regular speech, and I use it for the convenience or to intentionally add ambiguity, (e.g. to avoid embarrassing situations or to withhold information).

A subject in the sentence is missing

The following sentences would all be correct:

那本书**我**找了很长时间也没找到.

那本书**他**找了很长时间也没找到.

那本书**大卫**找了很长时间也没找到.

We omit subject all the time in dialogues, but only when it is strongly implied the subject is known

Example:

A: "我找到了不少作家X 未成名之前寫的書。"

B: "那作家X用不同筆名寫的那本你也找到了嗎？"

A: "那本书(我)找了很长时间也没找到。"

In this dialogue, B knows the subject in the last sentence is A himself. therefore omitting 我 is acceptable on B's point of view. Nonetheless, 那本书找了很长时间也没找到 is still ungrammatical

Note: You can replace 很长时间 with 很久. The meaning will not change

Tang Ho's answer is right. Strictly speaking, the subject should not be omitted, especially in writing in this case.

However, I'd also like to point out that colloquially the sentence might be ok to say when you could apply correct emphasis to it. I think most of non-native speakers could not make it.

As an exercise for identifying and correcting errors, we would consider that it's missing the subject.

那本书 is the object ( in fact 书 is the object, 那本 is 宾语)
没找到 is the predicate. ( in fact 找 is the predicate, 没, 到 are the 副词)
