Sure! The word "heathen" can be a bit complex, but let’s break it down.
In historical or literary contexts, "heathen" can be used to describe cultures or societies that were seen as uncivilized or primitive because they did not follow the major monotheistic religions. However, this use can be considered offensive or derogatory, so it's important to use it carefully and respectfully.
There aren't specific idioms or phrasal verbs that include "heathen," but you might hear phrases that refer to someone as "living like a heathen," meaning they are living in a way that is considered wild or morally questionable.
Using the term "heathen" can be sensitive. It can carry negative connotations and may be seen as disrespectful, especially when used to describe someone's beliefs.
