Un bambino di 10 anni vuole cambiare l’emoji con gli occhiali

Pronome diretto LA
Direct object pronoun LA

“ha chiesto alla Apple di cambiarla”
(asked Apple to change it)

In this sentence, the word la is a direct object pronoun and takes the place of the feminine noun emoji. Instead of repeating the noun, we use “la” to avoid repetition and make the sentence more fluent.
Normally it comes before the verb:

– Prendo la rivista e LA (= rivista) leggo (I get the magazine and read IT)
– LA vuoi o non LA vuoi? (Do you want IT or not?)

BUT: if there are two verbs, or the verb is in the gerund, imperative, or infinitive form, the pronoun follows the verb:

– Vai a prenderLA (= lei)! (Go get HER!)
– Vuoi la mela? PrendiLA (= mela)! (Do you want the apple? Take IT!)
