A Cantonese word, not Mandarin. It is the everyday third-person pronoun in Guangdong and Hong Kong speech — the rough equivalent of Mandarin 他 / 她 / 它. Add 哋 to make it plural ('they'). The Mandarin reading qú is rarely heard; in Cantonese it sounds like 'keui'.
Supplies the shape and a loose sound link. Standalone 巨 means 'huge'; here it carries no meaning, only serving as the writable body the Cantonese pronoun was built on.
