as a substitute I think

Answer 2

As a substitution

Step-by-step explanation:

A euphemism refers to a word or phrase that replaces another word or phrase that is considered more offensive, vulgar, blunt, unpleasant or impolite. Therefore, they function as a substitution for unpleasant words or phrases. Some examples of euphemisms are when we say "pregnancy termination" instead of "abortion", "Economical" instead of "cheap" and "tipsy" instead of "drunk."
