What does circularly mean?
"Circularly" is an adverb meaning in the form of a circle — describing movement, arrangement, or structure that follows a rounded, looping path rather than a straight line. It can describe literal geometry (a beam sweeping circularly, objects arranged circularly around a table) as well as figurative loops, most notably in logic: to argue circularly is to reason in a circle, where a conclusion rests on premises that themselves depend on that conclusion. The word derives from Latin circulus, a diminutive of circus meaning ring, and belongs to a family including "circle," "circular," and "circulate." In everyday conversation it is rare — speakers typically prefer phrases such as "in a circle" — but it remains standard in technical fields like mathematics, engineering, and physics (as in "circularly polarized light"), and in philosophical discussion of circular arguments.
In the form or shape of a circle; along or around a circular path.
"The electrons orbited circularly around the nucleus in the simplified model."
Common in technical contexts such as "circularly polarized" in physics.
(Of reasoning or argument) in a self-referential, circular manner, in which the conclusion is assumed by its own premises.
"He defended the rule circularly, citing the very policy it was meant to justify."
When someone says "we're going in circles," they're describing circular reasoning — and "circularly" is the precise word for it.

Etymology of circularly
"Circularly" is formed by adding the adverbial suffix "-ly" to "circular," which entered English from Latin circularis, derived from circulus, a diminutive of circus meaning "ring" or "circle." The underlying Latin root ultimately traces back to Greek kirkos/krikos, also meaning ring. Its cognates include "circulate," "circuit," and "circuitous," all sharing this same ring-shaped ancestry.

How circularly is actually used

Easily confused with circularly
"Circularly" describes motion or arrangement shaped like a circle, while "circuitously" describes an indirect, winding route that need not be round.
