Where does the work mick come from?

The term "mick" is a slang and often derogatory term used to refer to someone of Irish descent. Its origins are believed to date back to the 19th century, possibly derived from the common Irish name "Mickey." The term reflects the ethnic stereotypes and prejudices of the time, and its use is considered offensive. Historically, such slang emerged in contexts of Immigration and cultural tension, particularly in the United States and Britain.
