Siculish is the macaronic "Sicilianization" of English language words and phrases by immigrants from Sicily (Italy) to the United States in the early 20th century.
Forms of Siculish are also to be found in other Sicilian immigrant communities of English-speaking countries, namely Canada and Australia.
A surprising similarity can often be found between these forms, through either coincidence, trans-national movements of Sicilian immigrants, or more likely, through the logical adaptation of English using linguistic norms from the Sicilian language.
Some common Siculish terms and an explanation of their derivation (not necessarily common to all Anglo-speaking countries): Many children of Sicilian immigrants will often confuse actual Sicilian words for Siculish.
This will especially occur where both the Sicilian and English languages have basically the same word derived from Norman.
