My friend wants to get a tattoo, part of it will be in gaeilge, so I said I would help him and make sure his translation is correct before he permanently inks himself. The first half will be in hebrew. The second half will be in gaeilge. It will say "family" and "strength". However, strength is a hard word to translate, and all i've come up with is the word for physical strength, but not anything for strength among families. Does such a word exist? If not, can anyone suggest something more appropriate and coherent in irish?

"Neart" would be fine here; say, for example, with "mishpakha" above some image and "neart" below it. Putting the two words into any kind of grammatical relationship would be tricky.

For "neart", see the proverb:

Ní neart go cur le chéile.

Literally "is not strength until putting together"

I like the proverb above. I'll see what he thinks. Thanks!
