Morphology

one-quadrillionth = one + quadrillion (transparent) = one + quadrillion + th

The compound numeral 'one' + 'quadrillion' is clear and the suffix '-th' simply forms the ordinal/fractional form; meaning is recoverable from known components.

Etymology

One-quadrillionth comes from one + quadrillion + -th, where quadrillion is built from quadri- meaning 'four' (as in quadrilateral or quad) and million, so it is the fourth big step after a million and a very large number. The -th part means 'one part of', so one-quadrillionth is 'one divided by a quadrillion', a very tiny amount.
