To indicate that something is being done “accidentally” you take the past tense form and add one of the following special endings.
[-dọ³da²nv²³ɂi] “did accidentally…”
[-dọ³dị³sgo³ɂi] “habitually…-ing accidentally”
[-dọ³da] “let accidentally…”
[-dọ³di] “to accidentally…”
This ending is a composite of “Ꮩ-” + causative.
There does not exist a present tense form.
