Merry f
English: originally apparently an assimilated form of MERCY (SEE Mercy). In Dickens's novel Martin Chuzzlewit (1844), Mr Pecksniff's daughters CHARITY (SEE Charity) and Mercy are known as Cherry and Merry. Nowadays the name is usually bestowed because of its association with the adjective denoting a cheerful and jolly temperament (cf. HAPPY (SEE Happy)). In the accent of the central and northern United States there is no difference in pronunciation between MERRY (SEE Merry) and MARY (SEE Mary).
