I'm afraid I don't follow (no pun intended) your post at all.
1) How do prepositions come into this?
2) What is sentence a direct object of?
3) What makes you think that the adjective abnormal is a prepositional object?
Are we still talking about the sentence Does reading from right to left seem abnormal??
Reading is abnormal.
Reading seems abnormal.
Both is and seems are copula verbs (not "transitives") and abnormal is an adjective complement.
Hi,
I see what's happened now. I mixed up my predicate adjective.
I had a noun clause inside the preposition "from". Noun clause = right-to-left seem abnormal
Correction:
Turning sentence to a statement:
Sentence 1: "Isn't reading a sentence from right-to-left abnormal?"
1. "Reading a sentence from right-to-left is abnormal"
Noun clause = reading a sentence from right-to-left
Predicate adjective =
is abnormal
Noun clause + predicate adjective = independent clause
Sentence 2: "Doesn't reading a sentence from right to left seem abnormal?"
2. "Reading a sentence from right-to-left does seem abnormal"
Noun clause = reading a sentence from right-to-left.
Predicate adjective =
does seem abnormal
Noun clause + predicate adjective = independent clause
Sentence 3: "Isn't reading a sentence from right-to-left seem abnormal?"
3. "Reading a sentence from right-to-left is seem abnormal"
Noun clause = Reading a sentence from right-to-left
Predicate adjective =
is [STRIKE]seem[/STRIKE] abnormal
Noun clause + predicate adjective = independent clause
In sentence 3 you can easily spot two intransitives together (is seem), clearly incorrect.
In GoesStation post you could substitute noun clause for "this" example.
i. "This seems abnormal".
iii. "This does seem abnormal".
iiii. "This is seems abnormal".
Noun clause analysis:
Noun clause 1 = "(You) reading a sentence". Could be a transitive active (you=implied subject, reading=verb, and sentence = direct object).
Noun clause 2 = "reading a sentence" could be a gerund phrase.
I have some questions:
1. Is the noun clause a transitive active or a gerund phrase for the independent sentence analysed?
2. As an example, if we have a preposition with a noun clause inside the preposition acting as preposition of object, can the verbs from the independent sentence modify the object using the same method from GoesStation example?
