languages, also known as consistent NSLs, are languages that are characterized by rich subject agreement morphology where subjects are freely dropped under the appropriate discourse conditions. In some contexts, pro-drop in these languages is mandatory and also occurs in contexts in which pro-drop cannot happen for partial pro-drop languages. The following languages exhibit full pro-drop in their own distinct ways. Hindi South Asian languages such as Hindi, in general, have the ability to pro-drop any and all arguments. Hindi is a split-ergative language and when the subject of the sentence is in the ergative case (also when the sentence involves the infinitive participle, which requires the subject to be in the dative case), the verb of the sentence agrees in gender and number with the object of the sentence, hence making it possible to drop the object since it can be contextually inferred from the gender of the verb. In the example below, the subject is in the ergative case and the verb agrees in number and gender with the direct object. In the example below, the subject is in the dative case and the verb agrees in number and gender with the direct object. In the example below, the subject is in the nominative case and the verb agrees in number, gender, and also in person with the subject. Greek Subject pronouns are usually omitted in Greek, but the verb is inflected for the person and number of the subject. Example: Romance languages Like their parent Latin, most Romance languages (with the notable exception of French) are categorised as pro-drop as well, though generally only in the case of subject pronouns. Unlike in Japanese, however, the missing subject pronoun is not inferred strictly from pragmatics, but partially indicated by the morphology of the verb, which inflects for person and number of the subject. Spanish, Italian, Romanian, Catalan and Occitan can elide subject pronouns only (Portuguese sometimes elides object pronouns as well), and they often do so even when the referent has not been mentioned. This is helped by person/number inflection on the verb. The 3rd person singular and plural subject pronouns are often kept to denote and differentiate male and female subjects/genders. Spanish In Spanish, the verb is inflected for both person and number, thus expression of the pronoun is unnecessary because it is grammatically redundant. In the following example, the inflection on the verb ver, 'see', signals informal
