Middle Irish is a fusional, VSO, nominative-accusative language, and makes frequent use of lenition.
Nouns decline for two genders: masculine and feminine, though traces of neuter declension persist; three numbers: singular, dual, plural; and five cases: nominative, accusative, genitive, prepositional, vocative.
Verbs conjugate for three tenses: past, present, future; four moods: indicative, subjunctive, conditional, imperative; independent and dependent forms.
There are a number of preverbal particles marking the negative, interrogative, subjunctive, relative clauses, etc.
The following is an untitled poem in Middle Irish about Eógan Bél, King of Connacht.
