Final answer:
Using 'passed away' instead of 'died' or 'domestic goddess' instead of 'housewife' involves the use of euphemisms, a milder expression replacing harsher ones, which is a part of diction in English language.
Step-by-step explanation:
To describe someone as having 'passed away' instead of saying they 'died,' or to use 'domestic goddess' in place of 'housewife' is to employ a euphemism. A euphemism is a milder or less direct expression used in place of one that may be considered harsh or unpleasant. This figurative language is often used to address sensitive topics or to soften the impact of what is being discussed.
Euphemisms are a common aspect of diction, which refers to the choice and use of words and phrases in speech or writing. The effectiveness of diction depends on the appropriateness of word choices to convey a message clearly and impactfully without offending the audience. The use of euphemisms can be seen in literature, everyday conversations, and various forms of media.
