E is for emitter.

Two Es ar to distinguish it from Ve, which is the voltage of the emitter with respect to ground. Since Vcc has two Cs, they kept the convention of two letters for the negative (emitter) power supply voltage.

Vee is when you are using two voltage supplies to bias the transistor. You can use one, a Vcc and hook the emitter to ground. Or you can use 2. Vee is usually = -Vcc

It's the negative supply that the emitter would be eventually connected to (for an NPN) even if there's some network in the way.
