In Spanish, if you want to talk about your aunt or your friend's cousin, you cannot use apostrophes that will show who is in possession or in relation to the subject you are discussing. You must use the preposition 'of' to show possession. In Spanish, the preposition 'of' is:
Ella es la madre de Alex.
El es el padre de Manuel.
In Spanish, it is imporant to note that there is a change when you combine the preposition and article 'de' + 'el'. The becomes: 'del'.
El es tio de + el chico. El es tio 'del' chico.
For other preposition and article combinations, nothing needs to be done.
de + el = del
Ex. Ella es tia de las chicas.
