What does transient mean?
Transient means lasting for only a short time. It is used when something appears briefly and then disappears, such as a transient medical symptom, a temporary technical failure, or a short-lived increase in activity. The word is especially useful in formal, academic, scientific, and professional writing, where it conveys brevity more precisely than simply saying “short.” It can also suggest something that passes through a place or stage without lasting there. As a noun, a transient is a person or thing that remains only briefly, although this use is less common in everyday English. Transient should not be confused with transitional: a transient phenomenon is temporary, while a transitional one is connected with a change from one condition to another. The related noun transience describes the quality of being short-lived, and transiently is the standard adverb form.
Lasting only a very short time; temporary or brief.
"The power surge was transient and did not cause lasting damage."
Common in formal, academic, technical, and medical contexts.
A person or thing that exists or stays only briefly.
"The town’s transient population increases considerably during the festival."
Less common than the adjective use.
The plural is used mainly for people or things that stay or exist only briefly.
"Several transients were given shelter at the community centre."
Transient comes from Latin for “to pass across,” so the word carries the idea of something passing through rather than remaining.

Etymology of transient
Transient entered English in the late 16th century from Latin transiens, the present participle of transire, meaning “to pass over” or “to pass across.” The Latin verb combined trans-, meaning “across,” with ire, meaning “to go.” Its relatives include transit, transition, and transitory, all reflecting the same idea of passing or movement across.
