What is the definition of a chucker lathe? How does it differ from an enginelathe or a turret lathe?

In purest form, spindle hole closed off* and no tailstock. Meant for "chucking" short parts so chuck hole might as well be closed (to keep coolant out of spindle bore), and no need for a tailstock. Usually a turret type lathe, but can be gang tooling if CNC.
*unless it's something like a Hardinge HC, which uses 5C collets and by necessity of it's collet closing mechanism usually remains "open"

I'm aware of two things that are called "chuckers:"
Some people refer to second-operation lathes as chuckers - lathes that do not have all the features of an engine lathe or a big turret lathe.
Second, automatic chuckers. These are similar to automatic screw machines, except they are not (usually) bar fed. Each part must be loaded by hand - hence, chucker. Hardinge makes (made?) a chucker that has feed rate and dwell set by knobs instead of cams, and a couple other companies do as well.

A chucker by definition is a lathe without a tailstock. It can have a through hole like a Hardinge or W&S chucker, or not, like some Kummer chuckers.
The rest of the configuraton doesn't really matter. Unless you are talking about multi spindles, then a chucker would strictly have no provision for feeding bar, but may or may not have a through hole.
