doéirig

From dí- (“from”) +‎ at·reig (“to rise”) (without the infixed pronoun). Although this verb did not survive as such into modern Irish, the modern language does use the same component parts in the expression éirigh de (literally “to rise from”) to mean “abandon”.

• IPA^(key):

do·éirig (prototonic ·dérig, verbal noun déirge)

1. to abandon, forsake

Note: the future and the present subjunctive have the same form, as do the conditional and the past subjunctive. The forms are listed here as being future/conditional, but in context they could also be present/past subjunctive.
