Question 1 with 1 blank el carro tuyo es azul. (yo) 1 of 1 es rojo. question 2 with 1 blank el televisor nuestro es pequeño. (us

ArbitrLikvidat [17]

According to the context and following the model, using the possessive form the sentences are written as follows:

El carro tuyo es azul/ El carro mío es rojo.

El televisor nuestro es pequeño/ El televisor de ustedes es grande.

La impresora mía es rápida/ La impresora de ella es lenta.

La computadora suya es vieja/ La computadora tuya es nueva.

Los teléfonos suyos son caros/ Los teléfonos nuestros son baratos.

Translation:

Your car is blue/My car is red.

Our TV is small / Your TV is big.

My printer is fast/ Her printer is slow.

His computer is old/ Your computer is new.

Their phones are expensive/ Our phones are cheap.

<h3>What is the possessive form?</h3>

It is the one that expresses possession or belonging and there are two types, on the one hand the possessive determiners that are placed before the noun and on the other hand the possessive pronouns that are placed after the noun.

Its main function is morphematic: they express the category of person and number, modifying a noun and imprinting a sense of belonging to something or someone.

Therefore, we can conclude that possessives are related to personal pronouns, since they indicate which person owns something or someone.
