Berries,
I recently began to wonder what the masculine form of the name [name]Saoirse[/name] would be. Saoir? Saor? I’m toying with the idea of using this as a MN to honor my ancestors, but I am by no means knowledgeable about Gaelic proper names.
Help? Thoughts? [name]Both[/name] would be much appreciated. 
I think it’s [name]Seoirse[/name]. Well, I don’t think Seoirse is the masculine form of Saoirse, but it’s a very similar male name in Ireland. I don’t think there’s a specific masculine form of Saoirse. But I’m not Irish, so I might be wrong! NB. Seoirse is pronounced shor-sha.
There isn’t really one, the same way there’s no male equivalent to [name]Aoife[/name] and Caiomhe.
My understanding is that saorise is an everyday word in Gaelic, meaning ‘freedom’ (with a decidedly political bent). It’s used just as commonly as the English word freedom:
freedom of choice = saoirse rogha
freedom of payments = saoirse íocaíochtaí
freedom of the press = saoirse an phreasa
freedom of employment = saoirse fostaíochta
freedom of establishment = saoirse bhunaíochta
degree of freedom of trade = méid saoirse trádála
Irish is a gendered langauge, in that nouns are inherently feminine or inherently masculine. You can’t change it.
[name]Saoirse[/name] is a word name, so there is no male form of it. [name]Seoirse[/name] is a similar name. Pronounced “Shore-sha”, its the Gaelic version of [name]George[/name]. It might appeal to you. Good luck!
There is no male form. It’s the Irish word for freedom.
No male form I’m afraid!
