That's what I think is true.
I am in Being ("in Beijing" = adverb phrase = predicate adverb)
He is a student (predicate noun)
You were with them ("with them" = adverb phrase = predicate adverb)
He is somebody (predicate pronoun) that I know.
That's what I think is true.
But not a subject complement, right? Because those are nominal, and which leads to this question: why can't next be a preposition here, Who is next? (aside from what's obvious: it doesn't have an object, but particle prepositions can occur without an object in phrasal verbs, right? They're often called adverbial in that position, though, to account for it.)
That is, non-linking forms of the verb BE take adverbs in the predicate, but the form and function of those adverbs aren't always the same. For example,
She's in the house.Form: prepositional phrase <nominal>Function: adverbial <tells us where>So, given that adverbs give off this kind of duality, why couldn't next in Who's next? be a preposition in form, that is, be nominal and thereby privy to the category "subject complement"? Why is it called a predicate adverb?
In short, why does the verb BE have to be split into linking and non-linking kinds?
What's the difference in meaning here?
Adverb: The person is next => Adjective: the next person
Adjective: the next person => Adverb: The person is next.
Me, too, Justin. Me, too.
I don't sell Reader's Digest but the dictionary is worth the fairly stiff price, though it does contain very few errors (but many less well-researched or authored dictionaries do contain not a small number of sometimes even fundamental errors, including website dictionaries).
I've never heard of a predicate adverb, I'm afraid. All I know about the verb be is as follows:
be [linking (copular) verb]
My boss is always late. - the predicate adjective (late) modifying the subject (my boss)
be [intransitive verb taking an adverbial]
The leaves are everywhere. - everywhere doesn't modify the subject (the leaves) since it is an adverb here, and it's only adverbs, as far as I know, that can modify verbs, not adjectives
The point is that there are two different verbs of be, and you mixed them up, I guess.
By usage (or function), there are:
(a) Noun phrases (including appositives and complements);
(b) Adjective phrases;
(c) Adverb phrases.
By construction (or form), there are:
(a) Absolute phrases, consisting of nouns only (one or more), and their modifiers (adjectives modifying nouns, and adverbs modifying adjectives) if any;
(b) Phrases headed by a Preposition;
(c) Phrases starting with an Infinitive preceded by to (often also preceded by a pronoun or adverb, such as what, which, who, whom, whose, when, where, how, why);
(d) Phrases starting with a Continuous Participle or Perfect Participle (sometimes preceded by a noun, pronoun, or adverb)
