Unlike Mandarin那 (nà), Cantonese嗰 (go2) cannot be used alone without a following classifier.
In the now-obsolete简化字总表,個-个 is listed in the first table in whichnon-analogizable pairs of simplified and traditional Chinese characters are collected. In the current standard通用规范汉字表, neither嗰 nor𠮶 is listed. Therefore,𠮶 is a nonstandard simplified form. However, it is still widely used in Cantonese dictionaries published in Mainland China.
