Explanation:
Possessive adjectives indicate belonging. These adjectives are divided into two groups of similar length, and the main characteristic of each is its location with respect to the noun:
* the atone possessive adjectives (also called weak) should always be positioned in front of the noun to which they modify, and they are the following: mi, mis, tu, tus, su, sus, nuestro/a/os/as, vuestro/a/os/as.
* Tonic possessive adjectives (also known as strong) should always be placed behind the noun they modify, and have a greater emphasis than the unstressed. They are the following: mío/a/os/as, tuyo/a/os/as, suyo/a/os/as, nuestro/a/os/as, vuestro/a/os/as.
