Yiddish pronouns have markings for case, person, and number. We used a nonhierarchical lex-type scheme to capture this. For example the lex-type for a a first-person, nominative, singular pronoun would be `1p-nom-sg-pron` and in general the lex-type of a pronoun is ``In the first person 'mir' can either refer to the singular dative or the plural nominative. In the first and second person plural pronouns, we see accusative-dative leveling, since in both cases "undz" and "aykh" are used respectively.

These are some examples of .


Our lex-types for first and second person pronouns handle this via [__TODO__].


Yiddish also exhibits agreement between third person pronouns and nouns for [__TODO__]. So, the pronouns 'er' and 'zi' can be assigned to a male or female person as well as inanimate objects that are masculine or feminine; if these do not apply, the noun is neutral and receives an 'es'. In their plural form, the third person pronouns show case-leveling and also lose gender markings so the homogenous 'zey' is used. 

Some examples of this include [__TODO__].

Our lex-types for third person pronouns handles this via [__TODO__].

1. Constituent Order

In declarative matrix clauses, what is the order of the major constituents (subject, verb, complements)?
Yiddish has V2 word order for the major constituents of a sentence (subject, verb, complement) like most Germanic languages. The verb constituent always need to be in the second position in the clause but anything can come first (subject, object, verb, adverb, etc.).

	a) `Du zingst.` You sing.
	b) `*Zingst du.` You sing.
	c) `Der man leyent dos bukh.` The man reads the book.
	d) `*Leyent dos bukh der man.` The man reads the book.

2. Auxiliary Verbs
			
Yiddish contains auxiliaries which occur before the verb. A simple VP consists maximally of one finite verb. All tenses and aspects are formed with an auxiliary (AUX) verb, in all other forms other than the present indicative. the main verb will occur in a non-finite form (infinite or past participle). The AUX precedes the main verb, bot in the main and subordinate clauses:

	a) `Du zingst.` You sing.
	b) `Du kenst zingen.` You can sing.
	c) `Du host gevolt kenen zingen.` You wanted to be able to sing.
	
3. Inflection: Number, Person, Gender and Case

Adjectives, verbs, and determiners and are marked for number. Some pronominal adjectives, those that directly modify a noun, are inflected to agree with the noun in number, gender, and case. Predicate adjectives remain uninflected. Some pronominal adjectives including `eyn` 'one', `keyn` 'none', and posseive pronouns such as `mayn` 'my, mine' display behavior opposite to those or ordinary adjectives: they are inflected for number, gender, and case when used predicatively. Yiddish verbs are also conjugated for number. 

    * Yiddish verbs are conjugated for person and number. 
    * Determiners have number.
    * The possessive determiner is never used with the plural case.
* Person
    * _Third person pronouns must agree in gender with the noun they refer to. Thus even inanimate objects are sometimes referred to as er or zi if they are masculine or feminine respectively. Neuter nouns receive es._
    * Yiddish verbs are conjugated for person and number.
* Gender (if applicable)
    * Determiners agrees in gender, number, and case with the noun it is used with.
    * Adjectives are inflected for gender. The neutral adjectives can have definite and absolutive versions which are vestiges of German's influence on Yiddish.
    * Pronouns (see 3p).
* Case
    * Yiddish has three distinct cases: nominative, accusative, and dative.
    * Case is usually expressed with affixes on nouns, determiners, and adjectives.
    * Nouns aren't usually inflected for case, though there are a few notable exceptions such as kinship terms (tate 'father', mame 'mother'):
        * Masculine nouns take the ending -n in the accusative and dative singular.
        * Feminine and neuter nouns take -n only in the dative singular.
    * Adjectives are inflected for case.
    
 
4. Agreement:
    * Yiddish exhibits four types of agreement: attributive-adjective & noun, subject & verb, determiner & noun, 3p-pron & noun.
    * Adjectives are inflected for case as well as gender and number. While attributive adjectives—that is, those that directly modify a noun are inflected to agree with the noun in number, gender, and case, predicate adjectives remain uninflected.
    * Third person pronouns must agree in gender with the noun they refer to.
    * The definite article (determiner) agrees in gender, number, and case with the noun it is used with.
* Rest of the NP
    * Determiners usually precede nouns.
    * Determiners usually optional only in interaction with adjectives does the obligatory / impossible distinction come out.
5. Lexicon
    * _Talk about yiddish morphology and why we chose to use stemmed words here._
    * Morphemes used for inflecting {verbs {1p, 2p, 3p}x{sg,pl}, adjectives for {number, gender, case}, nouns for case}.
            
###Unimplemented properties
* Auxiliary verbs.
* Ditransitive verb are not handled.
* Plurality in Yiddish is very irregular; there are multiple suffixes that indicated plurality and no way of predicting which nouns they will be paired with (163).
* Infinitives not handled.
* Attributive-Adjective & Noun.
* Nominalized adjective.
* Our singular determiners should be able to be used with plural words (the cats).
* Determiner & noun-phonology correlation ('an' only used before vowels).
* Optional/Obligatory/Impossible case in nouns (distinction only made when adjectives and proper noun).
* Possessive nouns.
* Past participle verb forms (used frequently).
* _Perfect tense for verbs? I think this is done periphrastically with auxillary verbs and past participle verbs both of which aren't implemented._
* Strong vs weak verb conjugations (unpredictable).
* Strong vs weak adjective declensions for neutral gender (depend on whether a determiner is used). 
* Strong vs weak noun declensions (weak is handled).
* Prepositional phrases.
* Clitics.
* Inflectional variants (Which ones?).
