How do animals are bad words in Italian? I lead you into the mysteries of zoology in the Italian language.
The dog, il cane, in its animal form is a loyal pet, but as a person, it is a disaster. If a person, especially a supposed expert, is un cane, it means that this person is very bad at doing something. It could be a doctor, dentist, engineer, or mechanic, have many academic degrees but still being un cane: just avoid it.
Pigs are a beloved delicacy to eat, but when it comes to language they are so bad as you can think: and still, anytime you can catch maiale or porco spoken in everyday casual conversation.
Un maiale or un porco is a morally dirty person, in a sexual way: it’s a noun that occurs sometimes in a standard conversation.
But it’s porco as an adjective that leads the list of most common bad words: just add porco to a substantiv and you’re swearing at different levels of vulgarity, starting by mentioning an stupid duck up to the most common blasphemy.
Porco cane!, porca l’oca!, porca vacca!, mean something like bloody dog, bloody duck and bloody cow. We already talked about cane, the disaster; oca, the duck, is considered stupid; vacca, a cow is a reference to a vulgar woman. They can be perceived as childish but many adults use those. Porco mondo is the neutral bloody world. With porca puttana, the vulgarity is already high, because the noun puttana (only feminine) means slut. Surprisingly, in the mostly catholic Italy it is very common the blasphemy against God, Dio, built up with porco as an adjective. Especially in some regions, it belongs to everyday language. Some people change the blasphemy into porco zio: nobody ever understood what the poor uncle (zio) did to become the politically correct replacement for the divine name, except the phonetic resemblance, of course.
Birds are interesting: the simple word uccello (bird), refers to the dick, the vagina is the sparrow, passera (female, with -a suffix). Un pollo, a chicken, as you can guess, is someone very fearful, stupid and who can be easily tricked. Un pappagallo is a talkative and not interesting person who repeats what someone else said (often, the tv).
