Congelato vs. ghiacciato vs. surgelato
The Italian language has three main words for 'frozen': 'congelato', 'ghiacciato', and 'surgelato'. While they all relate to freezing, each word has specific uses and connotations.
Congelato
'Congelato' is the most general term for frozen. It refers to anything that has been frozen, typically by refrigeration or exposure to very cold temperatures.
Ho comprato della carne congelata al supermercato.
(I bought some frozen meat at the supermarket.)
Il lago è congelato durante l'inverno.
(The lake is frozen during winter.)
Ghiacciato
'Ghiacciato' specifically refers to something covered in ice or frozen so cold that it forms ice crystals. It's often used for natural phenomena or beverages.
La strada è ghiacciata, guida con cautela.
(The road is icy, drive carefully.)
Mi piace il caffè ghiacciato in estate.
(I like iced coffee in summer.)
Surgelato
'Surgelato' refers to food that has been frozen very quickly at extremely low temperatures, often for commercial purposes. It's similar to 'flash-frozen' in English.
I piselli surgelati mantengono più nutrienti di quelli in scatola.
(Flash-frozen peas retain more nutrients than canned ones.)

(We bought a frozen pizza for dinner.)
Summary
While 'congelato' is the most general term for frozen, 'ghiacciato' specifically refers to ice formation, and 'surgelato' is used for rapidly frozen food. Understanding these distinctions helps in choosing the right word for different contexts in Italian.
