More about garth
The original meaning of the common noun garth, “an open courtyard enclosed by a cloister,” has been replaced by courtyard or quadrangle or just plain quad. Garth comes from the Middle English noun garth (also gard, gart and a half dozen other spellings) “enclosed courtyard or garden; a hedge or fence,” from Old Norse garthr. The Old English noun cognate with the Old Norse is geard “enclosure, enclosed space, court, dwelling, home” (geard is pronounced about the same as yard). The Old English and Old Norse nouns come from Germanic gardaz “house, garden,” from Proto-Indo-European ghordh-, an extension of the Proto-Indo-European root gher-, ghor- “to enclose.” The extended root ghordh- yields Old Church Slavonic gradŭ “city, garden” (as in the name Stalingrad “Stalin City”), Russian górod, and Polish gród, both meaning “city.” The extended root ghorto- yields Greek chórtos “enclosure, court,” Latin hortus “garden” (horticulture is the cultivation of gardens), Welsh garth, and Irish gort, both meaning “field.” Garth entered English in the 14th century.
