How can I identify the form and function of each constituent in this sentence?

They moved into the apartment together.

I don't know which one of these two possible analyses correct:

  1. They (noun, subject)
    moved (verb, predicate)
    into the apartment (prepositional phrase, non-central complement)
    together. (adverb phrase, adjunct)

  2. They (noun, subject)
    moved into (verb, predicate)
    the apartment (noun phrase, non-central complement)
    together. (adverb phrase, adjunct)

  • 2
    "They" (NP subject). "Moved into the apartment together" (VP Predicate); "Into the apartment" (PP complement of "moved"); "together" (prep as adjunct).

  • May I ask why the word 'together' is considered as a prep instead of an adverb?

    Right. Both right. As usual, there's more than one way to parse a sentence, and most people can do either one and still come out describing the same thing. That's the fact that defeats general rules -- you don't hafta do things the way the teachers say. There's lotsa different ways that work just as well. For some folks, it's obvious that (1) is the usual parse, for others it's (2), and plenty of others don't notice any difference, since they both work. Aug 21, 2022 at 16:27

    @arlo I disagree with the last comment. Neither of your analyses are right. The Predicate VP is the whole moved into the apartment together. Within the VP is the PP "into the apartment". Would you like a full answer instead of just comments?

    @arlo Not quite: as I said before the predicate is the whole of moved into the apartment together. "Three years ago" is part of the predicate but it's a PP, not an NP. I'll do a tree shortly.

1 Answer 1


They moved into the apartment together three years ago.

enter image description here

Note that some would treat "together" as a complement rather than as an adjunct.

  • Why is 3 years ago not an adjunct there? Aug 22, 2022 at 20:40
  • I have the same question. Why is '3 years ago' not an adjunct in this sentence?
