Appendix:Vietnamese words derived from historically affixed forms

Modern Vietnamese contains a number of lemmas and forms derived from historically affixed forms.

This article excludes the animate prefix since it did not produce new words.

Instrumental infix *-rn-
Proto-Vietic infix derived nouns from verbs. As some verbs in Vietnamese also became nouns through semantic extension, the meaning of the infixed words and the uninfixed nouns sometimes became synonymous.

Cases where roots were nouns
These cases are fewer and it is harder to pinpoint their history.

Causative prefix *pr-
Proto-Vietic prefix derived verbs from verbs.
