While Modern Irish only has two grammatical genders, Old Irish had a third. "(H)ed" was the neuter pronoun, and was the equivalent to the English "it".
In Modern Irish, "(s)ea" survives as a pronoun used only with the copula.
Of course, this is only my suggestion for a gender-neutral personal pronoun in Irish. I know many people use "siad/iad" as a gender-neutral option. I am not trying to make anyone use my set of pronouns, although if anyone wants to use them that would be welcomed (although as of writing this I have not finished working on them). Like with any word or term, "one speaker = one vote". Terms only spread if people want to use them/identify with them, so if no-one wants to use them then they won't and that's fine. I would be interested in seeing other people's ideas around gender-neutral pronouns and language in Irish.
| Subject | Sea | Sé | Sí | Siad |
| Object | Ea | É | Í | Iad |
| Emphatic subject | Seisean | Sise | Siadsan | |
| Emphatic object | Eisean | Ise | Iadsan | |
| Possessive | A | AS | AH | AU |
"A" (neut.) would cause no mutations of any sort. Compare "a" (masc.) which causes a séimhiú (S), "a" (fem.) which causes H-prothesis (H), and "a" (plural) which causes an urú (U):
In Old Irish, "a" (neut.) caused a séimhiú, the same as "a" (masc.), however I think the neuter pronoun should be given different mutation rules in order to distinguish the two.
One problem that arises with creating neo-pronouns in Irish is that 15 sets of prepositional pronouns must be made as well. In Old Irish, the neuter pronoun was conjugated the same as the masculine one, however, if we want to create a truly neutral option, then I think these forms must feel distinct enough from both their masculine and feminine counterparts.

As mentioned above, creating new gender-neutral language in the Celtic languages also requires generating a set of prepositional pronouns (which I have started to work on in the above table).
I have been told that in some dialects that "sea" is pronounced very similarly to "sé".
