courty

The word 'courtyard' is a tautological compound, where two elements with similar meanings were combined for emphasis. The first element, 'court', entered English via Old French from Latin 'cohors', which originally meant an enclosed yard and later came to signify the retinue or attendants within such a yard. The second element, 'yard', is a native English word from Old English 'geard', sharing a common Proto-Indo-European ancestor (gʰerdʰ-) with its Latin counterpart, both meaning 'to enclose'. Thus, 'courtyard' literally means 'an enclosed yard within an enclosed court', a redundancy that solidified the term's specific reference to an open area surrounded by buildings.

Structure: court (enclosed area) + yard (enclosed ground) court: From Old French 'cort', 'curt', from Latin 'cohors', 'cohort-' (enclosure, retinue). In this word, it functions as the core noun meaning an enclosed area. yard: From Old English 'geard' (enclosure, garden, court), from Proto-Germanic gardaz. In this word, it functions as a noun reinforcing the sense of an enclosed ground.
