Regular nouns can appear in two cases: nominative and genitive.

The base form of a noun is the nominative, which does not receive any marker.

The genitive is formed by appending the suffix to the word, e.g. ["dages"], "eng" => ["days"]])); ?>. The marker for the plural has to be applied first, e.g. ["dager(e)s"], "eng" => ["days'"]])); ?>.
