I have a tree with Celtic knots and I would like to add a two-word phrase or a single word beneath it (don't have room for more!)
I am still deciding on what I want but these are some words/phrases I am mulling over...

-Strength
-Perseverance
-Peresvered
-I am strong
-I persevered

I got my tree after a traumatic experience so I want it to represent that I persevered/ I can persevere, I am strong, etc.

Thanks so much!

Irish has several words for concepts like "strength", and one may be preferable to another in a given context, but for your purposes, these would work:

Strength: neart or treise
Either would be fine for your general meaning.

Perseverance: buanseasmhacht
If you need a shorter word conveying the general sense of endurance, then buaine would work.

Persevered: It can be hard in some cases to state a stand-alone past participle in Irish, and I can't think of a way to do it in this case.

I am strong: Tá mé i mo neart or Tá mé i mo threise
Again, either would be fine for your general meaning.

I persevered: Bhí buanseasamh agam
This works, in theory, but in Irish (as is often the case when compared with English) it seems to call out for more explanation as to what was persevered in, so maybe go with one of the others instead..
