Pyramid words are words which start at 2 letters but can be
extended to 7 letters and beyond. For example take the word loofahs, we start
with lo, next we get to loo, followed by loof, loofa, loofah and loofahs. Thus
by knowing loofahs we get to know a total of 6 words.
Other examples include:
Abasers, Amenders, Amusers, Barbers, Bingers, Chained,
Chiasmal, Daledhs, Divests, Erasers, Fasties,
Godsons, Hookahs, Jambees, Jamboks, Kaingas, Kinases, Lapsers, Maliced,
Mentors, Nursery, Parkiest, Poleyns, Reeders, Reposes, Singers,

and finally drooped. Other examples include:

Glaired, Hamates, Lemures, Mananas, Penates, Retapes, Scraped, Testates,
