What does vagile mean?
Vagile means able to move freely or actively, and it is especially common in biology and zoology. The word describes organisms, body parts, or cells that can locomote rather than remain fixed in one place. A free-swimming microorganism and a larva that disperses after hatching may both be described as vagile, while a barnacle, which remains attached to a surface, is sessile. Although vagile can be translated in general contexts by “mobile,” it is more precise when active movement is central to the description. The term is formal and specialized rather than part of ordinary conversational vocabulary. Its unusual sound and its broad application across zoology, microbiology, and anatomy make it useful for precise scientific writing. The related noun “vagility” names the capacity for free or active movement.

"Many free-living microorganisms are vagile, whereas barnacles remain attached to surfaces throughout their lives."
"The newly hatched larvae are vagile and disperse into the surrounding water."
"Although normally attached to the seabed, the organism releases vagile cells that can move independently."
Vagile is the zoologist’s word for an organism that can roam: a mobile microscopic traveler rather than a permanently anchored sessile creature.

Where does vagile come from?
Vagile comes from Latin vāgīlis, an adjective meaning “wandering” or “mobile,” derived from vāgāri, “to wander.” English adopted the specialized zoological meaning of being capable of movement. Words such as vagrant and vagary reflect the same broader Latin family of wandering or straying, while vague ultimately comes from Latin vagus, meaning “wandering” or “unfixed.”
