We often use the word "myth" as a synonym for "lie" or "untruth." do you believe this is correct?

The word ''myth'' is not used as a synonym for ''lie'' or ''untruth'', instead it is used more in the manner of ''imagined'' or ''unclear''.

The myth is something that is in general considered to be the product of someone's imagination, but also we can not neglect the fact that some of the people that created the myths actually believed in those things, so we can not just classify it as a lie or untruth.

Also, there's lot of myths that are still very debatable, as there has been some that turned out to be real, for some it has been an exaggerated depictions of real life things, while some are very uncertain as to weather they are just imagination or there's some real life basis for them. Whichever way it is, pretty much everyone enjoys a good myth and the mysticism it brings with it.

the answer is: apostrophe and allusion.

apostrophe refers to a poetic technique that is used to address an absent individual or an abstract idea/being. allusion on the other hand is a poetic technique that being done by making an indirect reference to other person with a high level of significance (could be historically or culturally significant)
