Inheritably is an adverb that speaks to characteristics or traits passed down through genetics from one generation to another. Some synonyms for the word include innately, inherently, and naturally. These all suggest qualities that are present at birth rather than being acquired through learning or experience. Other potential synonyms include hereditary, genetic, and inborn. Each of these words works to convey the idea that something is part of a person's essence, and cannot be removed or changed. When trying to convey the notion of something being part of someone at the most fundamental level, these synonyms can be incredibly useful.
