And the last first

About

Words with the first three or more letters repeated at the end, unless all letters are repeated (for those, see Isograms of lengths six, eight and ten). Overlaps are okay (alfalfa, entente), but words with only two letters repeated (headache) are excluded. For non-English and capitalized words with this pattern see And the first last.

There are only a few four letter sets (abra, muck, okey, over, pung, sing, tara, trin and wish) and fifty-nine three letter sets (aft, alf, ama, ana, ane, ant, ast, ate, bed, beg, ben, bic, cal, cha, der, des, dva, ens, ent, ess, fel, fen, gal, gan, haw, her, hot, ing, ins, int, ion, mas, men, mes, mic, nic, non, oke, ope, out, ove, phy, psy, ras, red, res, san, ser, sia, sta, tal, ter, tes, thy, tor, tza, und, uri, and xer).
