#### Word-level conjunction

Constituents that are labelled only at the word level (notably, verbs and particles) conjoin at the word level.

    (NODE (VB (VB here) (CONJ and) (VB vnderstonde))
          (ID CMAELR3,26.4))

    (NODE (VBD (VBD furnysshed) (CONJ and) (VBD garnysshed))
          (ID CMMALORY,2.34))

    (NODE (VBP (VBP brenne) (CONJ and) (VBP sle))
          (ID CMMALORY,29.917))

    (NODE (RP (RP in) (CONJ or) (RP out))
          (ID CMAELR4,2.24))

    (NODE (RP (RP vp) (CONJ and) (RP don))
          (ID CMMIRK,5.105))

For simplicity, categories that project phrases also conjoin at the word level, provided that all conjuncts consist of a single word. Since the constituenthood of the conjunction structure is already indicated by a phrasal tag, no additional word-level tag surrounds the structure, unlike in the case of verbs and particles above.

    (NODE (NP (N maydenhood) (CONJ or) (N chastite))
          (ID CMAELR3,26.8))

    (NODE (ADVP-LOC (ADV behynd) (CONJ and) (ADV before))
          (ID CMMALORY,14.403))

#### Phrase-level conjunction

When any of the conjuncts consists of more than a single word, the second and following conjuncts are labelled as CONJPs, headed by the conjunction, and adjoined to the first conjunct at the phrasal level, as illustrated in the following schema:

    (XP (XP (X first-conjunct))
        (CONJP (CONJ conjunction)
               (YP (Y second-conjunct)))
        (CONJP (CONJ conjunction)
               (ZP (Z third-conjunct) (Z more-of-third-conjunct))))

All phrasal categories are conjoined in the same way. Conjunction of clauses, which follows essentially the same pattern but presents special difficulties, is discussed separately below.

    (NODE (NP-SBJ (NP (D the) (N duke))

          (ID CMMALORY,33.1055))

#### CONJPs with empty heads

All clear cases of phrasal conjunction, including ones without an overt conjunction, contain `CONJP`. This is most common in cases with more than two conjuncts, where an overt conjunction appears only before the final conjunct. But there are also cases without any explicit conjunction at all (for example, the X NOT Y construction).

    (NODE (NP-OB1 (NP (N fayth))
                  (, ,)
                  (CONJP (NP (ADJ good) (N hope)))  <-- no CONJ in 2nd and 3rd conjuncts

              (, ,)

          (ID CMMALORY,10.298))

In general, sets of constituents (NPs, PPs, etc.) acting as a unit are treated either as appositive or conjoined, and this is indicated either by the presence of the extended tag `-PRN` (see Appositives and parentheticals), or by the presence of CONJP on the second (and following) constituents. The immediately following structure is therefore illegal:

    (NODE (WNP-2 (WNP (WD what) (N mede))		<-- illegal structure, no -PRN or CONJP
                 (, ,)
                 (WNP (WD what) (N blysse))
                 (, ,)
                 (WNP (WD what) (N coroune))))

    (NODE (WNP-2 (WNP (WD what) (N mede))		<-- corrected structure, with CONJPs
                 (, ,)
                 (CONJP (WNP (WD what) (N blysse)))
                 (, ,)
                 (CONJP (WNP (WD what) (N coroune))))
          (ID CMAELR3,26.14))

#### Conjunction of unlike categories

Conjuncts are generally of the same category, but not always. In the case of unlike categories, the category enclosing the entire conjunction structure is, by default, that of the first conjunct.

    (NODE (NP-OB1 (NP (N religiuse))
                  (CONJP (CONJ ant)
                         (PP (P of)
                             (NP (NP-POS (NPR Seint) (NPR$ Iames))
                                 (N ordre)))))
          (ID CMANCRIW,I.48.87))

    (NODE (NP-OB1 (NP (PRO$ his) (N aihte))

                         (NP (N sarinesse))))
              (CONJP (CONJ and)

          (ID CMVICES1,3.18))

    (NODE (PP (PP (P on)
                  (NP (D +dare) (OTHER o+dre) (N woreld)))
              (CONJP (CONJ and)

          (ID CMAELR3,30.123))

When two words that conjoin at the word level have different labels, a CONJP is added. In most cases of single-word conjunction, the difference between conjoining like and unlike categories is an artefact of our system of labelling rather than reflecting true conjunction of unlike categories.

    (NODE (RP (RP to)
              (CONJP (CONJ and)
                     (ADV fro))))

    (NODE (VB (VB witen)

          (ID CMMANDEV,30.737))

Cases involving the conjunction of unlike categories that result in morphological mismatches are treated differently; see backwards gapping.

#### Recursive conjunction structures

Conjunction structures can be recursive. We attempt to represent the (perceived) intent of the text, using various clues such as the distribution of conjunctions, punctuation, syntactic parallelism, and alliteration.

    (NODE (NP-OB1 (NP (N gold) (CONJ and) (N seluer))
                  (, ,)
                  (CONJP (NP (NP (ADJ precious) (NS closes))
                             (CONJP (CONJ and)
                                    (NP (ADJ vertuous) (N stones)))))
                  (, ,)
                  (CONJP (CONJ and)
                         (NP (Q al) (D +te) (N pompe)
                             (PP (P off)
                                 (NP (ADJ wordliche) (N blisse))))))
          (ID CMAELR3,28.68))

    (NODE (NP (NP (NP-POS (ADJ blacke) (NS$ shepis))
                  (NS skynnes))
              (, ,)
              (CONJP (CONJ and)
                     (NP (D a) (ADJ grete) (N payre)
                         (PP (P of)
                             (NP (NS bootis)))))
              (, ,)
              (CONJP (CONJ and)
                     (NP (NP (D a) (N boowe)
                         (CONJP (CONJ and)

          (ID CMMALORY,30.940))

In the absence of evidence for grouping, the default would have been to give the first example above the following non-recursive structure:

    (NODE (NP (NP (N gold))			<-- default bracketing
              (CONJP (CONJ and)
                     (NP (N seluer)))

              (CONJP (NP (ADJ precious) (NS closes)))
              (CONJP (CONJ and)
                     (NP (ADJ vertuous) (N stones)))
              (, ,)
              (CONJP (CONJ and)
                     (NP (Q al) (D +te) (N pompe)

                             (NP (ADJ wordliche) (N blisse)))))))

#### Shared modifiers

#### Shared pre-modifiers

When the first conjunct includes pre-head modifiers, it is possible in principle for conjunction to apply at the word level or at the phrase level. In order to indicate the (potential) attachment ambiguity, the second and following conjuncts are labelled `(W)ADJX, (W)ADVX,` or `(W)NX.`

| `(W)ADJX, (W)ADVX,` and `(W)NX` are used even when the attachment ambiguity is resolved by the context. Since the second conjunct in these cases is never taken to be a full phrase on its own, the first conjunct is never surrounded by phrasal brackets of its own.

Extraposition of a second (or following) conjunct from a phrase consisting of conjoined single words is treated in the same way. Although for simplicity's sake, these cases normally do not contain a CONJP, when extraposition is involved, a CONJP is introduced (motivated by the fact of extraposition itself). Apart from the CONJP, no additional phrasal nodes are introduced. As with the phrasal case just discussed, the extraposed CONJP is coindexed with an `*ICH*` trace.

Main clauses are separated even when conjoined. The clause-initial `CONJ` in the second and subsequent clauses is treated as a constituent of the clause, and an empty subject `(NP-SBJ *con*)` is included in the second and subsequent clauses.

#### Conjunction of embedded IPs

The absence of a VP level in our annotation system forces us to treat both VP and IP conjunction in the same way---namely, as IP conjunction. An empty subject `(NP-SBJ *con*)` is included in any non-first clausal conjunct when its subject is elided.

#### Right-node raising

In right-node raising constructions, such as SHE ASKED FOR, BUT SHE DID NOT GET, A RAISE, the incomplete IP is marked as a parenthetical (`IP-MAT-PRN, IP-SUB-PRN`, etc.). In addition, the incomplete clausal material immediately preceding the right-node raised constituent is coindexed (with a index preceded by an equal sign) to the clause from which its missing parts can be reconstructed. Within such incomplete clauses, no reconstruction at all is done. That is, no empty categories are included, and no information beyond part-of-speech and minimal phrasal labelling (including the annotation of grammatical functions) is provided. PPs in such clauses need not include a prepositional object.

#### Gapping

The treatment of gapping resembles that of right-node raising. The gapped clause is coindexed with the complete clause from which it can be reconstructed. If the gapped clause is sentence-final, it does not receive a `-PRN` dash tag.

If the gapped clause is clause-internal, it is labelled as a parenthetical, with the exact label (`IP-MAT-PRN, IP-SUB-PRN,` etc.) depending on how its dominating clause is labelled, just as in the case of right node raising. Gapping of this type is often used even without strict equivalence between the complete and the gapped clause. If the relationship is extremely loose, however, the second clause may be dominated by `FRAG`.

Cases involving the conjunction of unlike categories that result in morphological mismatches are treated as backwards gapping. In other words, the first conjunct and the conjunction are part of the coindexed clause (rather than the conjunction and the second conjunct, as is the case with ordinary gapping.

#### Clausal conjunction and shared modifiers

Because of the way that we split matrix clauses, shared elements interpreted as belonging to both clauses must be annotated as belonging to one clause or the other, or one of the clauses must be treated as parenthetical (see Conjunction of embedded IPs). For adjuncts, we take the former approach; for complements, the latter. As a result, pre-sentential adjuncts will appear to apply only to the first conjunct, while post-sentential adjuncts will appear to apply only to the second conjunct. The most common cases include clause-initial WHEN and IF clauses.
