Morphology

thousandth = thousand (transparent) = thousand + th

Formed by the standard ordinal/fractional suffix '-th' added to the cardinal 'thousand', so the meaning is directly predictable from the base.

Etymology

Thousandth comes from an old English word thousand meaning 'one thousand' plus the ending -th that turns a number into a part or an order. So a thousandth is literally one of a thousand equal parts.
