Morphology

zillionth = zillion (transparent) = zillion + th

The noun/ordinal sense is produced by adding the regular ordinal suffix '-th' to 'zillion', preserving the core meaning of an extremely large (unspecified) number or high position.

Etymology

Zillionth comes from the informal number zillion, which was created by copying words like million and billion to mean 'a very large number'. Adding the -th ending makes it a position or a thing in a list, so zillionth is used to mean 'an extremely large, unnamed number' or a very high place in a list.
