rannaigecht

1282.
Isaac (G. R.): Varia: I. deibide.
In Ériu 49 (1998), pp. 161–163.
On the terms rannaigecht ‘unitary-stanza-making’ and deibide ‘differentiated, disagreeing (form)', the latter representing a substantivised adjectival derivative from deibe ‘difference, variety, disagreement’ + adjectival de, vs. GOI §392, where it is suggested that deibide derives from de + bíthe ‘cut in two’.
