untailed
Without rear extension
Untailed describes something that lacks a tail, either naturally or by removal.
A breed of untailed cats, a species of untailed amphibians, or an animal whose tail has been docked: The untailed lamb wandered back to its mother.
The word sees occasional figurative use for things missing an expected trailing element.
