A curse word is a swear phrase that expresses anger, disappointment, astonishment, or surprise. A curse word can consist of a single word (example: darn! ) Or an idiomatic combination of words ( Zum Kuckuck! ). 
Definition of terms
Curse words need to be distinguished from the following similar types of words.
- A swear word gives a person a negative meaning and in this way offends or belittles them (example: fool ).
- A vulgarism is coarse, vulgar, obscene, and thus violated the sense of shame. Many curse words are also vulgarisms (example: shit! ), Other curse words lack the element of vulgarity (example: sapperlot! ). Conversely, vulgarisms that do not aim to dispel anger are not swear words (example: piss-warm beer ).
- A blasphemy is the sneer of certain beliefs of a religion. Many curse words are blasphemy at the same time. This effect particularly affects swear words in traditional Catholic cultures (example: Italian porco dio , "God [is] a pig"). 
In Italian , blasphemous curses predominate as general swear words , such as Dio cane ("dog god"), porco Dio ("god-pig"), Dio boia ("hangman's god"), or Madonna puttana ("mother god's whore "). However, these expressions can be modified euphemistically : porco Dio then becomes porco zio (“uncle pig”). These curse words are also used by the German-speaking population in South Tyrol (Northern Italy) through language contact with the Italian language group.
