Saur
Definition:
(n.) Soil; dirt; dirty water; urine from a cowhouse.
Example Sentences:
(1) We have identified a class of small mRNAs (approximately 0.5 kilobases), referred to as small auxin-up RNAs (SAURs), that increases in abundance within minutes after auxin application to excised elongating hypocotyl sections of soybean.
(2) Archaeologists in Kabul did a preliminary survey of the site, mapping it and digging test trenches, but before they could gather the enormous resources needed for a full-scale excavation, first the 1978 Marxist coup then the 1979 Saur Communist revolution and the Soviet invasion intervened.
