Italian pronunciation
Unlike English, Italian double consonants are pronounced differently than single consonants. They sound longer.
How to pronounce the Italian double consonants
Generally speaking, a written double consonant corresponds to a longer consonant sound or sound interruption in Italian. This applies to all types of consonants, from non-plosives such as m and r (they do not interrupt the flow of air coming out of your lungs) and plosives (b, d, hard g, p, t and hard c).
Mamma, sasso, tatto, pacco | Mom, rock, touch, package |
How do you pronounce a double consonant like T or S?
Pronounce attack. Now start pronouncing at… stop. Keep your tongue on your alveolar ridge (the soft palate just above your teeth). Hold it there longer than usual, then release… tack! There you have a longer consonant. With enough practice and listening, you will be able to get double consonants just right.
You will still be understood if you pronounce them as single consonants, but you will have to watch out for words that completely change meaning with the quality of their consonant!
Double S (SS) is always unvoiced, never voiced.
Bara, barra | Coffin, plank | |
Ano, anno | Anus, year | |
Casa, cassa | House, box |

Z is always double
The consonant Z is always pronounced double in Standard Italian, even if it is written as a single consonant. The double written form also exists, as in pazzo or pizza.
Pazzo, pizza | Crazy, pizza |

Following this rule, a word like spazio, space, is actually pronounced as if it were spazzio. The same can be said of any word ending in -zione, such as nazione and protezione.
Spazio, nazione, protezione | Space, nation, protection |
Z is not pronounced as if it were double when it follows a consonant, because it would sound awkward and hard to achieve.
Canzone, pranzo | Song, lunch |
This also applies to the beginning letter of a word following another word.
Lo zaino | The backpack |

GN is pronounced as if it were double
Unlike the Z rule, the pronunciation of GN as a double consonant can vary depending on your regional accent. For example, gn is not pronounced as if it were double in my accent (Western Emilia Romagna), but it is in standard Italian (the one you hear in dubbed movies, on the radio, and on TV).
Ragno, castagna, stagno | Spider, chestnut, pond |
Like Z, this rule also applies to the beginning letter of a word that follows another word.
Lo gnomo | The gnome |
SC (“sh”) sound is always doubled
This again depends on your regional accent, but in standard Italian, you should pronounce any sci and sce sound as if they were double. This rule, too, applies to the beginning letter of a word that follows another word.
Lasciami! | Let me go! | |
Lo sciame | The swarm | |
I pesci nuotano nell’acquario. | Fish are swimming in the aquarium. |
