The Akh — Transfigured Spirit
The successful dead became a shining, effective spirit — and the living sometimes wrote them letters.
Also: akh · ꜣḫ · transfigured spirit · blessed dead · glorified spirit · effective spirit
The goal of Egyptian funerary religion was for the dead person to become an akh: a 'transfigured,' effective spirit, glorified and powerful, dwelling among the gods or the eternal stars. Becoming an akh was not automatic; it required correct burial, ritual, and the union of the person's parts. An akh could even act on the living, who sometimes wrote letters asking a dead relative's akh for help.
In short
The akh — the 'effective,' transfigured, and blessed state of the dead, achieved through successful funerary ritual, in which the deceased becomes a luminous, empowered spirit among the gods and the imperishable stars.

How the idea developed across Egypt
Attested from the Old Kingdom (the verb sakh, 'to make into an akh,' i.e. to transfigure the dead); the 'Letters to the Dead' address the akh of relatives across several periods.
Ka, ba, and akh are distinct; the akh is specifically the achieved, blessed post-mortem state.
