In my conlang there are three degrees of animacy:
0.0 Inanimate -- unable to move under its own power and control
1.0 Vagile animate -- able to freely move its own entire body from one place to another, under its own power and control
0.5 Sessile animate or stabile animate -- able to move under its own power and control, but unable to move its whole body from one place to another under its own power and control.
I don't really know the best terms for degree 0.5 and 1.0.
"Vagile" is related to "vagabond", "vagrant", "vague", "vagus".
Quite a few people distinguish "mobile" from "motile" and think one of them means capable of voluntary movement while the other means capable of movement, but not necessarily voluntary movement. But they disagree which means which.
IIANM some few people think one of them means capable of translocating its entire body while the other only means capable of moving; but IIANM, if that's the case, they also don't agree on which is which. Maybe I misunderstood.
For 1.0, I considered "loco-motive animate" or "auto-mobile animate", as well as "translocatively animate". I think I prefer "vagile animate" to both of those.
An entity can be capable of moving other things than itself -- for instance, the water in which it lives -- under its own power and control; and also be able to move its body from one place to another; but not be vagilely animate.
Consider an artificially intelligent crane1
, that, once it's in its work position, can move freight or whatever from wherever it picks it up to wherever it needs to put it down. Imagine that it also has an engine and treads or tracks or wheels by which it can be moved from one worksite to another. It might automatically control its projecting arm or beam, derrick, winch, hoist, davit, block and tackle, etc., to do its day-to-day work, but need to be driven by a human driver from one worksite to another on those infrequent occasions when it needs to be re-located.
That would be "sessile animate" in my conlang.
So my question is:
What are the best terms to call these?
