A nakade is a play inside an eye space which prevents it becoming two (or more) eyes.

Example

[Diagram]
Three points.

Black can kill this three-point eyespace by playing nakade at B1,



Unsettled eyeshapes are those eyeshapes where a nakade is possible.
Basic living eye shapes are those where a nakade (in one move) is not possible.
Dead eyeshapes are those where a nakade is not needed: the group is already dead.

Be aware however that these basic shapes ignore two major effects:

For several possible reasons, the eye space may contain more enemy stones. Any eye shape which is filled with stones so that almost filling it with a killing shape is inevitable, is dead. These patterns are listed at killable eyeshapes.

A combination of both circumstances can be found at Biggest known eye space for which there is a nakade
