===== Fourth and fifth declensions =====
There is little attestation as the Umbrian fourth or fifth declension. The fourth declension accusative singular was seemingly represented orthographically by the form {{Lang|xum|-o}}, which was often used to represent the ending {{Lang|xum|-um}} in Umbrian writings. Nominative and accusative plural forms are attested for the fourth declension neuter. It is likely that the ending was {{Lang|xum|-uā}}, although it would have been represented orthographically in various ways according to the standard Umbrian writing conventions for final {{Lang|xum|-ā}}. Other forms attested to a genitive singular ending in {{Lang|xum|-or}}, a dative singular in {{Lang|xum|-o}}, an ablative singular form in {{Lang|xum|-i}}, and a dative-ablative plural in {{Lang|xum|-us}}. One locative form is attested: {{Lang|xum|'''manuv-e'''}}.{{Sfn|Buck|1904|p=132}} The majority of attested Umbrian fourth declension terms appear feminine or neuter, however the Umbrian form {{Lang|xum|'''mani'''}} appears masculine in contrast to the feminine Latin cognate {{Lang|xum|manus}}.{{Sfn|Buck|1904|p=132}} Few fifth declension forms are attested in Umbrian: the accusative plural "{{Lang|xum|iouie}}," the dative-ablative plural "{{Lang|xum|iouies}}," the dative singular "{{Lang|xum|auie}}," the ablative singular "{{Lang|xum|re}},"{{Sfn|Pitts|2020|p=9}} and the form "{{Lang|xum|'''ri'''}}," which serves as both a dative or ablative singular.{{Sfn|Buck|1904|p=133}}
