👉 Synanthema is a term used in philosophy and linguistics to describe a situation where two or more people, often related by blood or marriage, are unable to communicate effectively due to differences in cultural, social, or biological characteristics. In this case, it refers to situations where one person has the same genetic makeup as another, resulting in a lack of understanding or communication between them. Synanthematous relationships can be found across many different cultures and societies, with some being more common than others.
