Aijin Wrote:Why would you need to use the objective case for 'consider'? I understand why it sounds unnatural in the other constructions, and I agree, but I'd need some evidence that 'consider' requires the objective cause for it to be grammatically correct
(because I am difficult like that)
I looked it up. It seems that with certain main clause verbs, the embedded subject pronoun requires an object case. (Verbs like saw, heard, prove, believe, etc.) It’s called an ECM (Exceptional case marking) construction. “The verb in the main clause is said to exceptionally assign the accusative case it can give to its own direct object to the subject in the embedded clause instead.”
This was traditionally called, “after its Latin equivalent, the accusativus cum infinitivo, or a.c.i. This name indicates that the morphological form of the subject in the infinitival clause is unexpected for a subject. In Latin, this subject has case morphology that is usually reserved for direct objects, so-called accusative case (rather than the case normally showing up on subjects, the nominative case). Although English has lost the morphological case system it had in older stages of the language, we can still see a remnant of this when the subject of an a.c.i. clause is a pronoun, as this pronoun shows up in object form rather than subject form.” (There are apparently alternative grammar theories for why this happens.)
I'll try to set out how this applies to the grammar point in this thread. Grammar ain’t my thing … so substitute whatever alternative grammar labels you prefer.
Some verbs can take a complete embedded clause as their object/ complement. Here, the object of the main clause is [Mark is a student]. This complement clause has its own subject and finite verb.
I think [Mark is a student].
I think [he is a student]. (clause subject pronoun takes nominative case)
I think [that Mark is a student].
Some verbs can take a reduced clause as their object complement or clause with a non-finite verb (such as the infinitive verb "to be".) This thread has been discussing one particular type of 'non-finite complement clause' which is the ECM construction.
We consider [Susan a good candidate].
We consider [Susan to be a good candidate].
We can paraphrase this sentence by using “that” + a complete finite clause:
We consider [that Susan is a good candidate].
But if we remove “that”, then the "is" changes to "to be" and the embedded clause becomes a non-finite clause with these types of verbs. So it is not correct to say: We consider [Susan is a good candidate].
“Susan” is the subject of the embedded clause. “Susan” alone is not the object of the main verb - we aren’t considering “Susan”, we are considering [Susan to be a good candidate]. Despite this, Susan’s pronoun form takes the accusative (object) case in these types of sentences:
We consider [her a good candidate].
We consider [her to be a good candidate].
Also, the following sentence is also correct:
We consider [Susan as a good candidate].
The embedded clause has its own subject (Susan) and complement (a good candidate). We can use “as” when the complement is a nominal complement.
I consider him a friend.
I consider him as a friend.
I took that to mean it works for nouns only. So we might say “I consider her pretty”, but not “I consider her as pretty.” but who knows.
I hope that’s useful. I wanted to thank Aijin and Magamo (and Masaman) again for their invaluable contributions here.
To Magamo: Don’t worry, I wouldn’t consider this stuff "easy". Most native speakers survive on 'gut feel' and have to look up specific grammar points if asked. btw - I'd keep 'consider' in your repertoire.
