Origins

Structurally similar to the gerundive suffix -undus. It reflect an old gerundive formed to the element formed to the -b- of the imperfect or future tense. If this theory is accepted, then the term could continue earlier Proto-Italic *-βuwont(i)nos, from Proto-Indo-European *-bʰuH-ont-(i)nos, itself a combination of the root Proto-Indo-European *bʰuH- (“to become, to grow”) and one possible pre-form of the gerundive suffix, which may reflect *-ont- (participial suffix) + *-is (noun-forming suffix) + *-nós (adjective-forming suffix). The putative Proto-Italic pre-form *-βuwont(i)nos could follow a development from *-βuwont(i)nos > *-buwondos > *-buwundus > *-būndus > *-bundus. The final shift from *-būndus > *-bundus would constitute an example of Osthoff's Law in Latin. Compare -undus and -cundus.
