Arrays are frequently treated as having a frame of length 1. With this frame, the array has cells of rank 1 less than the rank of the array. These cells are the items of the array.
The items of a list are the atoms in the list. The items of a table are the rows in the table. The items of a rank 3 array are the tables in the array. An array is the list of its items.
An atom has one item, itself.
The # (tally) of a noun is the number of items in the noun.
