Morphology

eighty = eight (transparent) = eight + ty

Formed by the standard numeral-forming suffix '-ty' meaning 'times ten', so the relation to 'eight' is direct and predictable.

Etymology

The word eighty comes from eight plus the ending -ty, which means 'ten' and appears in words like twenty and thirty. So eighty literally means 'eight tens', which is why it equals 80.
