sod (n.1)

"turf, slice of earth with grass on it," mid-15c., apparently from Middle Dutch sode "turf," or Middle Low German sode, both related to Old Frisian satha "sod," all of uncertain origin. Perhaps the notion is water saturation and the group is related to sog. The (old) sod "Ireland" is from 1812.

term of abuse, 1818, short for sodomite (also see sodomy). British colloquial sod-all "nothing" is attested from 1958.

c. 1400, "to cover with sod," from sod (n.). Related: Sodded; sodding.
