The only attested Danian inflection is yrc the plural of urc “orc” (Ety/ÓROK). This plural seems to be the result of i-mutation, similar to Noldorin plural nouns, but it is unclear whether this plural was representative of plural formation in Danian or an irregular form. Such plurals did occur in the Old English language that inspired Danian: OE “mūs”, plural “mȳs” (Modern English “mouse” and “mice”). However, normal plurals were formed through the suffixes in Old English, though the suffix varied by noun case rather than simply being “-s” as it is in modern English.

There are two names that might provide examples of Danian plurals or class-plurals: Danas “Danians” and (East Danian) Leikvir. Absent further information, however, nothing conclusive can be said about these examples.
