My mother said to me today, "Only Americans have 'yards' everywhere else it is a garden" (as in "go out in the yard") I don't know that to be strictly true, but because of her comment I had to look up the word. Interestingly enough, "yard" and "garden" come from the same word.
"ground around a house," O.E. geard "enclosure, garden, court, house, yard," from P.Gmc. *garda (cf. O.N. garðr "enclosure, garden, yard;" O.Fris. garda , Du. gaard , O.H.G. garto , Ger. Garten "garden;" Goth. gards "house," garda "stall"), from PIE *gharto- , from base *gher- "to grasp, enclose" (cf. O.E. gyrdan "to gird," Skt. ghra- "house," Alb. garth "hedge," L. hortus "garden," Phrygian -gordum "town," Gk. khortos "pasture," O.Ir. gort "field," Bret. garz "enclosure, garden," and second element in L. cohors "enclosure, yard, company of soldiers, multitude"). Lith. gardas "pen, enclosure," O.C.S. gradu "town, city," and Rus. gorod, -grad "town, city" belong to this group, but linguists dispute whether they are independent developments or borrowings from Gmc. Yard sale is attested by 1976. M.E. yerd "yard-land" (mid-15c.) was a measure of about 30 acres. Yardbird "convict" is 1956, from the notion of prison yards; earlier it meant "basic trainee" (World War II armed forces slang).
