Ná glacse fal fleadh má ghníos
Dod dheartháir dil ar a thíocht ón mbás.

This means "don't bear a grudge". I can find fal and fala, but not fal fleadh. Could it be that banquets often led to fall-outs and grudges, and so fal fleadh means "a grudge"?


I now think the word order confused me:
ná glacse fal - don't take a grudge
fleadh má ghníos: if I have put on a banquet etc
