EUPHEMISM, in rhetoric, a figure 

 which expresses things, in themselves 

 disagreeable and shocking, in terms im- 

 plying the contrary quality : thus, the 

 Pontus, or Black Sea, having the epithet 

 ee|fve>$, i. e. inhospitable, given it, by rea- 

 son of the savage cruelty of those who 

 inhabited the neighbouring countries, 

 this name, by Euphemism, was changed 

 into that of Euxinus. In which significa- 

 tion nobody will deny its being a species 

 of irony : but every euphemism is not 

 irony, for we sometimes use improper and 

 soft terms in the same sense with the pro- 

 per and harsh. 



EUPHONY, in grammar, an easiness, 

 smoothness, and elegance in pronuncia-

 there are abundance of "examples, in all 

 language*.
