Ó hIonmhaineáin, or in modern spelling Ó hIonúineáin, anglicized Noonan
But this is a Munster name.
Ó hIonmhaine / Ó hIonúine is an alternative version

Mac Ionmhain / Mac Ionúin
This is an Ulster (and Scottish) name, anlicized McKinnon, or Love

All these names are based on the adjective ionúin = beloved, dear (old spelling ionmhain) or the abstract noun ionúine (ionmhaine) = dearness, affection.

Ó Cárthaigh and Ó Searcaigh, which mean "descendant of Cárthach", resp. "of Searcach", both meaning originally "loving", now more prominent in Ó Searcaigh because there's still the noun searc = love
Both are Ulster (and Connacht) names.

Mac Cárthaigh is a Munster name.

This is fantastic! Thank you so much once again!

Nílim cinnte fé sin. Dar léi féin, "Niamh Cinn Óir, is é m'ainm...", nó dar leis an leabhar seo (leathanach 238, vearsa a 3) leis an Ossianic Society.



I've learned something new here.

Dar léi féin ...

In "Leabhar Filidheachta Fá Choinne na Scoil" (1909) atá "Chinn-óir" séimhithe:
http://corpas.ria.ie/index.php?fsg_word=chinn-óir&fsg_class=W&fsg_pos=N&fsg_function=10
In "Gaethe Gréine" (1920) "Chinnóir" chomh maith
http://corpas.ria.ie/index.php?fsg_word=chinnóir&fsg_class=W&fsg_pos=N&fsg_pp=Both&fsg_years=1600-1926&fsg_function=10
Agus 63 sampla le "Niamh Chinn Óir" (gan fleiscín) in "corpas.focloir.ie"
http://focloir.sketchengine.co.uk/auth/ ... =%3Ddoc.id
(Níl ann ach cúig shampla gan séimhiú)

I've got a few more, if that's alright:

1. "When I ride into battle, it is always to win." The part that needs to be in Irish is "When I ride into battle..."
2. "Come back to me, my love." I'd like to use the endearment "a rún" for "my love," if it's appropriate in the context (between lovers).

I also have a few quick questions:
1. Is the endearment "a leanbh" appropriate between a parent and a child, as well as between lovers? Is it something similar to "my darling?"
2. What about "a stor" or "mo stoirín?" Is it okay for friends as well as lovers, or only lovers?
3. How does “a rúnsearc" differ from "a rún?"

Again, thank you so very much for any insight!!

No, it means my child in the literal sense. It wouldn't be used between lovers that I know of.




Just lovers, not friends. This one you could use with a child, though. Be aware, again, of the difference between a and mo. The former is to address the person, the latter is possessive of the person. So, if you're talking to the person and calling them this endearment you would use a stór and a stóirín. Note the length mark over the "o" in both stór and stóirín.




It's a different word. It's like the difference between calling someone my sweet and my sweetheart.

Thank you so much! Really appreciate it!

Three more phrases I'd love a little help with!

1. When addressing a person, it is a mhuirnín or mo mhuirnín?
2. What is the proper way to say "I love you" to one's beloved? Is it Tá grá agam duit?
3. How would you say "Take me home."

Thanks again!!!

a mhuirnín
There's a need to use the particle "a" in addressing. And this particle contradicts the use of "mo"

Yes

Tabhair abhaile mé.

Thanks so much, Labhrás!
