a tagged pointer is a common example of a tagged union, where the primary type of data to be stored in the union is a pointer. Often, the tag in a tagged pointer will be "folded" into the data representing the pointer, taking advantage of one of the following properties of pointers:
Pointers to certain types of data will often be aligned to the size of the data (4 bytes, 8 bytes, etc.), which leaves a few bits of the pointer unused. As long as code that uses the pointer properly masks out these bits, the pointer can be tagged with extra information.
The virtual memory system in most modern operating systems reserves a block of logical memory around address 0 as unusable. This means that, for example, a pointer to 0 is never a valid pointer and can be used as a special null pointer value.
