What does the word "saire" mean? Is it Gaelic?

Answer 1

I think the word is French, perhaps a proper name like Smith or Jones. I knew of a French fellow who's last name was spelled the same way. If the spelling was sair, that's Scottish Gaelic for "sore" or "serve".
But I did just find this in my search on the web:
Sir Saire de Quincy Magna Charta Surety

I then found this:
The Saire River is a small coastal river which takes its source with the Mesnil-with-Valley (Handle) and crosses the north-eastern point of Cotentin (Valley of Saire in Normandy) to be emptied between Réville and Saint-Vaast-la-Hougue.

I bet you'd find the name in a book of Japanese Baby Names that would also give their derivative.

Answer 2

Scottish word "sair" also sare, saer means: 1. Causing physical pain or distress; 2. Causing mental distress or grief; 3. Involving hardship, difficulty, danger

Answer 3

I looked it up in two dictionaries and on Focal an Lae webpage.
Couldn't find in in Irish Gaelic.
However, I am not as fluent as I was once, and your spelling may be off.
