Did you know that Old Irish Gaelic contains three separate genders, specifically feminine, masculine, and neuter? Old Irish Gaelic also contains three numbers, those being singular, plural and dual. The dual form however only appears occasionally in distinct grammatical structures. For those of you not familiar with Old Irish Gaelic or it's structure, it is the native Irish language used between the 6th and 10th centuries. The language would eventually evolve into Middle Irish, and undergo many rapid changes.
