In Irish it's 'laoch'.
another answer: In ancient Gailic it's cathaoir
(no, that means chair or throne)
I researched it and the site I found said that "cath" was the word for war and it preceaded words that meant anything to do with specific war or acts of war. YOu are the expert. Go ahead and delete my answer. :)
laochra
banlaoch / ban-ghaiscíoch
Laoch (warrior, hero); curadh (warrior, hero, champion); gaiscíoch (warrior, hero).
In Irish "Celtic warrior" is "gaiscíoch Ceilteach".
I can't find the word as spelled.It could be an laoch (the warrior, hero, champion)?
cuh-rah "Champion", yes. For "hero" or "warrior" I would go with Laoch (lay-och)
Irish: laoch, gaiscíoch Scots Gaelic: Laoch or Cathach
The Scottish Gaelic phrase for "fire warrior" is "laoch teine." So, if you want to sound all fancy and fierce while talking about a fiery warrior in Scottish Gaelic, just drop that phrase like it's hot. You're welcome.
