Morphology

one-millionth = million (transparent) = one + million + th

The ordinal/fraction-forming suffix '-th' attaches to 'million' to form 'millionth'; 'one' then specifies a single unit, a fully compositional and regular formation.

Etymology

The word one-millionth comes from the parts one and million plus the ending -th, and it means 'one part of a million'. That's why it is the fraction '1/1,000,000', similar to how one-half is '1/2' or one-fourth is '1/4'.
