23 Foraicimib 7 Deachaib/ Extra Groups and Syllables: Bacht, lact, fect, sect, nect; huath, drong, tect, caect, quiar,; maei, gaeth, ngael, strmrect, rect; ai, ong, ur, eng, ing. These are supplementary lists of syllables which the Oghamist had to learn as part of his grammatical training. Several of the alphabets are lists of this kind.
