Introduction
This document presents background information on the clausal modifiers library of the Grammar Matrix Customization System (Bender et al., 2002; Bender and Flickinger, 2005; Bender et al., 2010) and provides instructions for filling out this section of the questionnaire. General instructions for using the questionnaire can be found here.

Clausal Modifiers
Drawing from the typological survey of Thompson et al. (2007) and description in Li and Thompson (1989), we divide clausal modifiers into three basic strategies: Those marked by a free subordinator morpheme (1), those marked by a free subordinator morpheme pair (one in the subordinate clause and one in the matrix clause) (2), and those marked by special verbal morphology (but no free subordinator) (3).
(1) Ame ga agaru to, Gon wa hotto shite ana kara haidemashita
rain NOM stop when Gon TOP relief performing hole from snuck.out
`When the rain stopped, Gon got relieved and came out of the hole' Japanese [jpn] (Thompson et al., 2007)
(2) Yīnwèi tiān hēi le, suǒyǐ wǒ méi chǖ-qu
because sky black CRS so I no exit-go
`Because it had gotten dark, I didn't go out.' Mandarin [cmn] (Li and Thompson, 1989)
(3) Yaʔáʃ ŋéŋi $uŋá-l kí-ʃ pu-wá-qi-pi
man leave.remote woman house.ACC her-sweep-PURP
`The man left in order for the woman to sweep the house' Luiseño [lui] (Thompson et al., 2007)
Further variation among clausal modifier strategies is described under Options.
Options
The Clausal Modifiers page allows users to define any number of clausal modifier strategies, which may vary in the following ways.
Clausal Modifier Position
The clausal modifier can occur strictly before, strictly after or freely before or after the constituent it modifies.
Clausal Modifier Attachment
The clausal modifier can attach to verb phrases, sentences or either.
Subordinate Predication
The subordinate predication can be contributed one of three ways, which correspond to the three basic subordinator types described above:
- by a free subordinator morpheme
- by a free subordinator morpheme pair
- no free subordinator (in which case the predication is associated with a particular morphological form)
If the strategy uses a free subordinator morpheme or free subordinator morpheme pair, the user may add any number subordinators and their corresponding predications. If there is no free subordinator, the user may only add one predication for that strategy.
The free subordinator morpheme pair includes a subordinator in the clausal modifier, which has the same options as a free subordinator, and a ‘pair’ morpheme in the matrix clause which has its own set of options.
Subordinator Position
A free subordinator can occur strictly before, strictly after, or freely before or after the VP or S it attaches too. Note that occurring freely before or after is only compatible with the adverb analysis described below.
Subordinator Type
The user may choose to analyze the subordinator as the head of its clause (as an adposition) or as an adverb. Typically we recommend that the user treat the subordinator as a head unless there is evidence otherwise. Such evidence includes attaching at the VP level or occurring at both the beginning and end of the clause.
Subordinator Attachment
If the subordinator is the head of the subordinate clause, it attaches to the subordinate clause at the S level. If, however, it is an adverb, the user may select VP or S attachment (or both).
Subordinator Pair Adverb
Under the subordinator pair analysis, the adverb in the matrix clause has the same position and attachment choices as the adverb subordinator.
Special Morphology
Whether or not the strategy has a free subordinator, the user can add special morphological constraints on the subordinate verb. Current supported features include:
- FORM
- NMZ (see MatrixDoc/NominalizedClauses)
- ASPECT
- MOOD
- Syntactic features (under HEAD) defined on the MatrixDoc/OtherFeatures subpage)
Some common examples include:
- A non-finite verb is required: check the box to add FORM on the Other Features page. Then click “Add a feature” in the clausal modifier strategy and select FORM non-finite.
- Subjunctive mood is required: define the values for MOOD on the Tense, Aspect, Mood Subpage. Then select MOOD subjunctive for the clausal modifier strategy.
- The subordinate clause must be nominalized: Define a nominalization strategy on the Nominalized Clauses subpage. Then add nominalization ”your strategy” to the clausal modifier strategy. If the language uses different nominalization morphemes in different clausal modifier strategies, we recommend creating a feature on the Other Features page (under HEAD) that is for both nominal and verbal categories. Associate this feature with the morphological rule that adds the nominalization feature and with the appropriate clausal modifier strategy.
Subject Sharing
If the subject is shared between the matrix and subordinate clause and is unexpressed in the subordinate clause, the user should check “Yes” for subject sharing.
Analyses
Adposition subordinators
If the subordinator is an adposition, the customization system will add this lexical supertype:
adposition-subord-lex-item := single-rel-lex-item & norm-ltop-lex-item &
[ SYNSEM.LOCAL.CAT [ MC -,
HEAD adp &
[ MOD < [ LOCAL scopal-mod &
[ CAT [ HEAD verb,
VAL.COMPS < > ] ] ] > ],
VAL [ SUBJ < >,
SPR < >,
COMPS < [ OPT -,
LOCAL.CAT [ MC -,
VAL.COMPS < > ] ] > ] ] ].
We create the following subtype of adposition-subord-lex-item if the subordinate clause is verbal (a separate subtype is added if the subordinate clause is nominalized)
subord-with-verbal-comp-lex := adposition-subord-lex-item &
[ SYNSEM [ LOCAL [ CAT [ HEAD.MOD < [ LOCAL [ CAT.HEAD verb,
CONT.HOOK [ LTOP #mod,
INDEX #index ] ] ] >,
VAL.COMPS < [ LOCAL [ CAT.HEAD verb,
CONT.HOOK.LTOP #comps ] ] > ],
CONT [ HCONS <! qeq &
[ HARG #h1,
LARG #mod ], qeq &
[ HARG #h2,
LARG #comps ] !>,
HOOK.INDEX #index ] ],
LKEYS.KEYREL [ ARG1 #h1,
ARG2 #h2 ] ] ].
Adverb subordinators
If the subordinator is an adverb, the customization system will add this lexical supertype:
adverb-subord-lex-item := no-rels-hcons-lex-item &
[ SYNSEM.LOCAL.CAT [ VAL [ SUBJ < >,
SPR < >,
COMPS < > ],
HEAD adv &
[ MOD < [ SUBORDINATED none,
LOCAL intersective-mod &
[ CAT [ MC -,
HEAD verb ] ] ] > ] ] ].
We define a unary rule to add the subordinate predication and to add the matrix clause to the subordinate clauses MOD list.
adv-marked-subord-clause-phrase := unary-phrase &
[ SYNSEM.LOCAL [ CAT [ MC -,
VAL [ SPR < >,
COMPS < >,
SPEC < >,
SUBJ #subj ],
HEAD adp &
[ MOD < [ LOCAL scopal-mod &
[ CAT [ HEAD verb,
VAL [ SPR < >,
COMPS < > ] ],
CONT.HOOK [ LTOP #mcl,
INDEX #index ] ] ] > ] ],
COORD - ],
C-CONT [ RELS <! arg12-ev-relation &
[ ARG1 #mch,
ARG2 #sch ] !>,
HCONS <! qeq &
[ HARG #mch,
LARG #mcl ], qeq &
[ HARG #sch,
LARG #scl ] !>,
HOOK.INDEX #index ],
ARGS < [ SYNSEM.LOCAL [ CAT [ HEAD verb &
[ MOD < > ],
VAL [ SUBJ #subj,
SPR < >,
COMPS < >,
SPEC < > ] ],
CONT.HOOK.LTOP #scl,
COORD - ] ] > ].
Subtypes of this rule contain a PRED value and are associated with a clause that has the appropriate adverb via the SUBORDINATED feature.
Morphologically marked subordination
For morphological subordination, the customization system adds a unary phrase structure rule similar to adv-marked-subord-clause-phrase, that is sensitive to the relevant morphological property. Abstracting away from the constraints specifying that property, the rule is as follows:
morphological-subord-clause-phrase := unary-phrase &
[ SYNSEM.LOCAL [ CAT [ MC -,
VAL [ SUBJ #subj,
SPR < >,
COMPS < > ],
HEAD adp &
[ MOD < [ LOCAL scopal-mod &
[ CAT [ HEAD verb,
VAL [ SPR < >,
COMPS < > ] ],
CONT.HOOK [ LTOP #mcl,
INDEX #index ] ] ] > ] ],
COORD - ],
C-CONT [ RELS <! [ ARG1 #mch,
ARG2 #sch ] !>,
HCONS <! qeq &
[ HARG #mch,
LARG #mcl ], qeq &
[ HARG #sch,
LARG #scl ] !>,
HOOK.INDEX #index ],
ARGS < [ SYNSEM.LOCAL [ CAT [ HEAD verb,
MC na-or-+,
VAL [ SUBJ #subj,
SPR < >,
COMPS < > ] ],
CONT.HOOK.LTOP #scl,
COORD - ] ] > ].
Subtypes of this rule contain a PRED value and the appropriate feature constraints for the morphological property.
Combined strategies
For each strategy, we create subtypes of the lexical types and unary rules to constrain the strategy according to the user’s choices. These are specified on the lexical type or unary rule as detailed in the following table.

Paired subordinators
We add the SUBPAIR feature to associate subordinators with their matrix pair. basic-head-mod-phrase-simple passes SUBPAIR up from the non-head daughter, while the head-subject and head-complement rules pass it up through the head-daughter. The item on the subordinate clause’s MOD list is specified to have a particular SUBPAIR value and the root symbol must be [SUBPAIR none] to ensure that matrix pairs don’t occur without a subordinate clause.
Note: when adding morpheme pairs to the customization page, if the matrix adverb is added first, the predicate for the subordinate adverb will be auto-populated with _adverb+subordinator_subord_rel. This follows from the if+then construction in the English Resource Grammar. For example, if ‘then’ is the matrix adverb and ‘if’ is the subordinator, the predication will be _if+then_subord_rel.
