I would love to get a gift for my husband with the Scottish gaelic translation for "honor truth and duty". Can someone help me find the correct translation? Thank you!

I suggest - Onoir, firinn agus dleastanas - but wait for confirmation from the others.

Thank you.

Did you really mean "Honor truth and duty", or did you mean "honor, truth and duty"? The two sentences are very different.

Franc,
Conservatively, Gaelic repeats "and" and "or" between every item in a list. The comma thing is a bittie "bearlachais"

Great question. I'm looking for honor, truth, and duty. Thank you for asking me to clarify.

Ah well, I'm very sorry about the comma.

Looks good, but there are a couple of typos, one of which is hard to see in a small font, so I've enlarged the font. As to the first correction, spelling is still in flux to some extent, but that spelling seems to be the most common one currently.

Onair agus fìrinn agus dleastanas

You can also abbreviate the word agus ("and"), as is very commonly done,so variants could be:

Onair is fìrinn is dleastanas
Onair 's fìrinn 's dleastanas
or you can vary what you use (sometimes resulting in a nicer rhyme or beat):
Onair 's fìrinn agus dleastanas
Onair agus fìrinn 's dleastanas

It's not that spelling is unstable as much as it is that a lot of the uses of "onoir" are in clan mottos, old prayers etc, and thou shalt not edit thy clan's motto. Some people are happy updating song lyrics, others less so. Pretty much anything being written now would be "onair", though.
