-zet

See also: Appendix:Variations of "zet"

Albanian

Inherited from Proto-Albanian *w(ī)džatī, from Proto-Indo-European *wídḱm̥ti (“twenty”).^[1]^[2] The initial z-, corresponding to the *-ḱ-, in place of **dh- is explained by the adjacency with the original *w.^{[n 1]}

-zet

-twenty
njëzet, dyzet ― twenty, forty

trezet, katërzet, pesëzet (dialectal) ― sixty, eighty, hundred

^ Compare possible parallels in zë / zâ (“voice”), zot (“lord”), samë (“dog shit”).^[2]
