Traditionally, the people of Għargħur spoke in their own dialect. This dialect, like others on the island of Malta, is highly endangered. This is mainly due to the influence of the media, in which the dialect of the harbour area is used, and an education system which discourages the use of dialects. A socio-cultural stigma associated with dialects also contributed to the gradual demise of the dialect. As older generations stopped talking to their children in dialect, the dialect started dying out.
