What does derestrict mean?
Derestrict is a verb meaning to remove an official restriction or limit from something, most commonly a speed restriction on a road or stretch of railway. When a road that has been limited to fifty miles per hour during roadworks is restored to the national speed limit, it is said to have been derestricted. The word is formed by adding the negative prefix de- ('to remove, reverse') to restrict, and it belongs largely to formal and technical registers. It is especially associated with British usage, appearing frequently in traffic orders, transport planning documents, and motoring journalism. By extension, derestrict may occasionally be applied to other kinds of regulatory limits being lifted, though such figurative use remains uncommon. Its noun form, derestriction, names the act or process of removing a restriction. The word is useful precisely because English lacks a compact everyday alternative: phrases like 'lifting the speed limit' must otherwise do its work.

Etymology of derestrict
Derestrict combines the prefix de-, from Latin indicating removal or reversal, with restrict, which derives from Latin restrictus, past participle of restringere ('to bind back, confine'), itself from stringere ('to bind tight'). The word arose as a technical coinage in twentieth-century British transport administration to name the act of lifting speed limits. It shares its Latin root restringere with relatives such as restriction, restrictive, and constrict.
