In my blood
Meaning
This idiom describes a skill, passion, or characteristic that is so deeply ingrained in someone's nature that it feels inherent, hereditary, or unchangeable.
Origin
The concept of blood as the vessel for inherited characteristics, temperament, and even destiny, runs deep through ancient human history. Before the science of genetics, people universally believed that qualities like courage, artistry, or a knack for farming were literally passed down through a family's bloodline. This powerful, visceral belief that one's essence and inherent talents resided within their very veins gave rise to the phrase "in my blood." It vividly describes a passion, skill, or characteristic so fundamental and innate that it feels inseparable from who a person is, as if biologically destined to be part of them, echoing a time when blood was the ultimate marker of identity and lineage.
Examples
