corner: [13] The idea underlying corner is of a ‘projecting part’ or ‘point’. It came via Anglo- Norman corner from Vulgar Latin *cornārium, a derivative of Latin cornū ‘point’ (‘point’ was in fact a secondary sense, developed from an original ‘horn’ – and Latin cornū is related to English horn). Other English descendants of cornū are corn ‘hard skin’, cornea [14], cornet [14], originally a diminutive form, and cornucopia [16], literally ‘horn of plenty’.
