"It is childish!"
Criancice is pejorative . Infantil is a thing made for children. Like a book for children 'um livro infantil'
I had no idea it was "criancice" because I wasn't taught that word yet. Same thing with pronouns in direct/indirect object position. And the word "to love." All in this section. What happened?
What's wrong with saying pueril? Is that word not really used in Portuguese?
