-ann

• -eann (slender form)
• -aíonn (second-conjugation form (broad))
• -íonn (second-conjugation form (slender))
• -nn (first conjugation form (contracted))

From Middle Irish -ann, -and, -enn, -end, where it was a third-person singular present conjunct ending. It started as part of the root in prototonic verb forms like ·éirenn (“pays”), ·fothlann (“removes”), ·tesband (“is lacking”), ·fuband (“attacks”), ·dérband (“prevents”) and was later reinterpreted as an ending.[1] This -nn originates in the Old Irish class B IV presents in -(n)aid, before that from the Proto-Celtic presents in *-nāti, and finally from the Proto-Indo-European nasal infix presents in *-né-H-ti, which are formed from roots with a final laryngeal. See Proto-Indo-European *-né-.
