`oñga`arl'- The pre-Celtic Language

I have finally thought of a name for my pre-Celtic people: the `oñga`arl'
(/'?oNga?arl~/, where l~ is vocalic /l/), formed from `on "heart" and garl'
"earth, land", so Heartlanders. I was sorely tempted by the Pictish idea
proposed by Jörg, but the `oñga`arl' predate even the Picts. Not only that,
I don't see them surviving past the Celtic invasion at all.

However, I have decided to make the language nominative/abosolutive, and I
want an unorthodox way of marking the absolutive case. I would like to know
how some natlangs do it, any suggestions would be welcomed. I don't want a
suffix or an infix, though, it's too run-of-the-mill. Thanks a lot.
