What does cambered mean?
Cambered describes something that has been given a slight upward curve — an arch across its width or along its length rather than being perfectly flat. Its most familiar application is to roads and bridges: a cambered surface rises towards the centre so that rainwater drains to the edges rather than collecting in puddles. The word is equally at home in aeronautics, where a cambered wing has a curved cross-section that helps generate lift. As a technical term it belongs mainly to engineering, construction, and motoring writing, but it appears in general descriptive prose too, often with connotations of careful craftsmanship or purposeful design — a curve put there deliberately, not by accident. Related to the verb 'to camber', it can also serve as a past participle: a plank may be described as cambered once it has been shaped that way. For anyone reading plans, driving commentary, or aircraft specifications, 'cambered' is the precise, established word for that subtle crown of curvature.
Curved slightly upwards; arched so that the middle is higher than the edges, as of a road, beam, or wing.
"The cambered roadway channelled rainwater neatly into the gutters."
Frequently preceded by modifiers such as 'slightly' or 'gently', since the curve involved is usually shallow.
Having been given an upward curve; the past form of the verb 'camber'.
"Each floor joist had been cambered to offset the load it would carry."
Every motorway you've ever driven on is secretly a very shallow hill — cambered so rain rolls off instead of pooling under your tyres.

Etymology of cambered
The word derives from 'camber', which entered English in the early seventeenth century from French 'cambrer', meaning to arch or bend, itself ultimately connected to the notion of a vaulted chamber (compare Latin 'camera'). It was first used of shipbuilding and carpentry before extending naturally to road engineering and then to aerodynamics in the twentieth century.

Usage notes
Mostly technical or descriptive in register — common in civil engineering, motoring, and aviation writing; rare in everyday conversation. In British English especially, drivers talk of a road's 'camber' and describe it as cambered when it slopes away from the centre.
Don't confuse with
'Chambered' means divided into rooms or compartments (as in a nautilus's chambered shell), while 'cambered' means curved or arched upward like a road or wing.
