What does circumscribe mean?
To circumscribe means to set boundaries around something — to restrict its extent, scope, or freedom — and, in geometry, to draw a shape around another so that the outer figure encloses the inner one, touching it at defined points. The word is formal in tone and appears frequently in legal, political, and scholarly writing: constitutions circumscribe the powers of officeholders, budgets circumscribe ambitions, and traditions may circumscribe individual choice. It carries a neutral-to-restrictive connotation; whatever is circumscribed is confined rather than destroyed, held within limits rather than eliminated. In mathematics, a circumscribed circle passes through all the vertices of a polygon, enclosing it exactly. The word derives from Latin circum- ('around') plus scribere ('to write or draw'), literally 'to draw around'. Its precision makes it valuable wherever careful boundary-drawing matters, from geometry classrooms to constitutional debates.
verbTo restrict, limit, or confine something within bounds; also, in geometry, to draw a figure around another so as to enclose it while touching it at points.
- To limit or restrict the scope, range, or activity of something.
- (Geometry) To draw a line or figure around another, enclosing it while touching it at specified points.
"The new regulations circumscribe the authority of local councils."
"Strict budget constraints circumscribe what the research team can attempt."
"A square can be circumscribed about a given circle, touching it at four points."
In geometry, one circle can kiss another perfectly at every point — that's what it means to circumscribe, and English borrowed the idea for limiting power and freedom too.

Etymology of circumscribe
Circumscribe comes from Latin circumscribere, formed from circum ('around') and scribere ('to write, draw'), originally meaning 'to draw a line around'. It entered English in the early modern period, first attested in the late 16th century, carrying both its geometric sense of drawing a figure around another and its figurative sense of marking out limits. It shares the scribere root with inscribe, describe, transcribe, and subscribe, and the circum- root with circumference and circumvent.
