Morphology

eightieth = eighty (transparent) = eighty + th

Standard ordinal formation from the cardinal 'eighty' (orthographic change y → i before the suffix), so the meaning '80th' is directly derived.

Etymology

Eightieth comes from the number eight plus the ordinal ending -ieth, the same way we make words like 'thirtieth' from thirty. So when you use eightieth as an adjective, you mean it is the one in the '80th' position.
