CAMBRIDGE HEXAGON

A Cambridge hexagon with nine clues is shaped like one of the examples below. If there is a different number of clues, the length of each side is half that number, rounded up; for example, one with eleven clues has sides of six letters.

CHEVRON STAR

A chevron star is a compound form in which four chevrons meet at a shared central point. In this example, letters forming the interior borders of the chevrons are shown in boldface.

In the hollow diamond, the size of the hollow section should be such that the four longest words form a square.

ENNEAGON

The enneagon has nine sides. The right, and inverted right, enneagons are inherently double.

FAN

In a fan, words read across and diagonally. The two longest diagonal words always read from top to bottom. The others all slope to the left or right, as in a star. The length of each side is equal to half the number of clues. The fan is inherently double.

LATTICE

Lattices are windmills with an added framework of letters on the outside. Because these outer words contain a number of uncrossed letters, the formist should take particular care to clue these words straightforwardly.

OBLONG

An oblong is a rectangle sloped along a diagonal. The length of the longer sides is the same as the number of letters in the longest word.

OCTAGON

If an octagon has ten clues, its word enumerations are: 4, 6, 8, 10, 10, 10, 10, 8, 6, 4. If there are seven clues, it has the shape of the example below.
