The above list consists of words structured ABA, where A is a sequence of 2 or more letters and B of 1 letter or more. The concatenations A and B may be meaningless, but the final word must be non-esoteric, appearing in a respectable dictionary.

See how far ( maximal 2A+B) you can go, you will probably manage without my samples, but try to get an uninterrupted (lengthwise) listing of words from 5 letters up.
