dampproofing

انگلیسی

Etymology:damp (n.) early 14c., "noxious vapor in a coal mine, fire-damp, stifling poisonous gas," perhaps in Old English but there is no record of it. If not, probably from Middle Low German damp; ultimately in either case from Proto-Germanic *dampaz (source also of Old High German damph, German Dampf "vapor;" Old Norse dampi "dust"). Sense of "moist air, moisture, humidity" is not easily distinguished from the older sense but is certainly attested by 1706. proof (v.) 1834, "to test," from proof (n.). From 1950 as short for proofread (v.)
