Spanish Determiners - Possessive Determiners

Possessive Determiners

These are often known as possessive or genitive determiners. They are used before the noun they possess (and before the rest of the whole noun phrase, for example when an adjective precedes the noun). They agree in number with the noun, and sometimes in gender, too.

• 1st person singular (yo): mi(s)
• 2nd person singular (tú): tu(s)
• 3rd person singular (él, ella): su(s)
• 1st person plural (nosotros/as): nuestro/a(s)
• 2nd person plural(vosotros/as): vuestro/a(s)
• 3rd person plural (ellos/as): su(s)

Note the following:

• There is no distinction in number for the third person possessives (i.e. between "his"/"her"/"its" and "their").
• The possessive for usted and ustedes is su(s) as for other third-person pronouns. The ambiguity that this causes (especially considering that su(s) already covers "his", "her", "its" and "their") can be allieviated by treating usted(es) as a noun and thereby saying la casa de ustedes instead of su casa. It is also possible to disambiguate by saying la casa de él or la casa de ella, etc.

Dialectal variation:

• The archaic pronoun vos has the possessive form vuestro, just like vosotros does. However, in modern dialectal use, tu replaces vuestro. Therefore, an Argentinian would say Che, decime tu dirección rather than decidme vuestra dirección or dime tu dirección.
• Dialectally, usted/ustedes may replace tú/vosotros without any intention to be formal. The corresponding possessive determiner su(s) is used. Therefore, a Colombian may say Hijo, enséñeme sus deberes instead of Hijo, enséñame tus deberes ("Son, show me your homework").
