What does 'euphemism' refer to in literary terms?

In literary terms, a euphemism refers to a pleasant or mild way of expressing something that may be considered harsh, impolite, or unpleasant. It involves substituting a more agreeable expression for one that might provoke discomfort or offense. For example, using "passed away" instead of "died" is a common euphemism that softens the impact of the reality of death.

The other choices do not accurately define a euphemism. A type of poetry with strict rhyme refers to specific forms of poetry, like sonnets, which doesn't relate to the concept of using milder language. A recurring pattern of sounds pertains to literary devices like alliteration or rhyme, not euphemism. Lastly, a line of verse specifically refers to poetry and does not have a connection to the meaning of euphemism. Understanding euphemisms enhances comprehension of literary texts by highlighting how language can shape perception and meaning.
