This is a spellingbee word, which I could find only in an
article about Celtic. Only some of our Irish members may
comprehend the passage. I sure don't.

Two things should be pointed out when comparing the above passages. Firstly, B
recension speaks of announcing and increasing the truth, using ipv. 2 sg. forms of the
verbs. A recension corresponds to B only in having fsaig, ‘increase’, at the start of the
second clause, the rest of which is strikingly different. The collocation frinne frforboir,
‘a truly-powerful justice’, though not attested elsewhere, can be paralleled by the
connection of the adj. forbar and of its later derivative forbarach with nouns flaith,
‘ruler’, or flathius, ‘sovereignty’, attested in the later language e.g. flaith forbair, ‘a
strong chief’, in a XVIIth century poem, O’Gr. Cat. 536.15; flathius forbarach frian, ‘a
productive and righteous reign’, LL 132a 36, in the poem by Fland Mainistrech R
