22   Adnominal clauses

Adnominal clauses are headed by adnominal predicates, and modify a following N, PRO, WPRO, Q, or NPR. With the exception of the short form of the copula and some fossilized forms, adnominal precidates are indistiguishable from the past and non-past conclusive forms of predicates. Adnominal clauses are divided into two groups: gapped and gapless. The first group are those adnominal clauses which contain a gap which corresponds to the head noun (i.e., the modified noun). From a gapped adnominal clause A with predicate B modifying a noun C we can “reconstruct” a sentence in which C occupies the gapped position and takes a grammatical role with respect to either B or some other predicate contained in A. This type of “gapped” adnominal clause is called a relative clause and is tagged IP-REL. The gap and its function are annotated with a trace. An IP-REL used in series with another modifier can be used to show how a relative clause contains a gap:

22.1   Adnominal clauses with traces (IP-REL)

In an IP-REL clause a trace *T* occupies a constituent-initial position (see section 6 for details) and is accompanied by information to specify a grammatical role. (Functional elements may need to be added to a N restored to an argument position, although they are not marked on that N when it is the modified head.) In (227), the trace has subject grammatical role (NP-SBJ *T*):

An example in which the trace has object grammatical role:

An example of a long distance dependency, where the trace has subject grammatical role in a clause embedded inside the relative clause.

An example where the modified noun corresponds to positions in each of two coordinated clauses (in this annotation, a superordinate IP-REL has a trace, and an embedded IP-ADV, disambiguated by CONJ, also a trace). The trace immediately dominated by IP-REL comes after CONJ.

22.2   Adnominal clauses without traces (IP-EMB)

In the second group of adnominal clauses, the modified noun has no direct grammatical role with respect to the predicate of the modifying clause, which itself is a saturated structure. This type of “gappless” adnominal clause is assigned the label IP-EMB.

     One common type of IP-EMB construction involves the modification of formal nouns. Given that many formal nouns (はず, こと, ため, etc.) rarely appear in unmodified form, and then only with particular meanings (為になる話; 事が運ばない, モノを言うのは金だ; etc.) it is clear that in a usage as a formal noun, an element cannot “reconstruct” into its modifying clause and is modified by IP-EMB. The following example shows the formal noun の nominalising an activity predication:

(234)
かけぶとんをはねのけるのは、まったく簡単だった。

( (IP-MAT (PP (NP (IP-EMB (NP-SBJ *pro*)
                          (PP (NP (N かけぶとん))
                              (P を))
                          (NP-OB1 *を*)
                          (VB はねのける))

          (AX だっ)
          (AXD た)
          (PU 。))
  (ID 107_aozora_Harada-1960))

     Accordingly, when a noun (e.g., 時, 間, 前, 後, etc.) is being used as a formal or relational noun and takes a saturated adnominal clause, that clause is tagged as an IP-EMB.

Here are more examples of formal nouns modified with IP-EMB:

     In general, nouns that can bear propositional content all can take saturated adnominal clauses: nouns denoting forms of speech, writing, thought, perception, sense, event, activity, disposition, cause, outcome, manner, depiction, etc. The class of “picture nouns” is included here:

(238)

‘A photo of a smiling child was put there.’

( (IP-MAT (PP (NP (IP-EMB (PP (NP (N 子供))

  (ID 1218_textbook_kisonihongo))

     Among the nouns commonly modified by IP-EMB are relational nouns such as 上, 下, 前, 後, 中, etc. The modifying clause specifies the value of the realtional noun.

     If a particle という or との intervenes between the adnominal clause and head noun, the clause is tagged IP-SUB instead of IP-EMB / IP-REL.

22.3   Internally headed relative clauses

Internally headed relative clause constructions are not very common, but when they are found, the annotation pratice is to add (PP (NP *T*) (P *.e*)) immediately to the left of the constituent (either NP or PP) that is coreferent with the modified head の:

22.4   Resumptive pronouns

When a modified N does not have any grammatical role with respect to the predicate heading a modifying IP, a pronoun or referring expression coreferential with the head can sometimes appear. This is a special case where the modifying IP is marked as IP-REL and the trace is put into an PP headed by (P ***). Situations such as these are annotated with identical binding information on the co-referential items:
