Once a ______ always a ______
Meaning
This phrase asserts that a person's fundamental character or a significant past behavior is permanent and will inevitably resurface or define them.
Origin
Long before psychology became a science, humanity grappled with the elusive nature of change. Could a scoundrel truly become a saint? Could a coward find lasting courage? The structure 'Once a ______, always a ______' isn't born from a singular event or dusty parchment, but from this very ancient human quest for predictability and an intuitive belief in the permanence of character. It reflects a profound, and often cynical, observation: that core traits, once exhibited, are incredibly difficult to shed, almost as if branded onto the soul. This phrase became a verbal shortcut, a conversational shorthand to encapsulate the folk wisdom that what's 'bred in the bone will come out in the flesh,' offering a definitive, if sometimes harsh, judgment on the immutability of a person's nature or habits. It speaks to our deep-seated need to categorize and understand, providing a comforting (or discomfiting) sense of certainty about human behavior.
Examples
- Even though he's changed careers, people still expect him to take charge because, once a leader, always a leader.
- My grandmother always warned me, 'Once a liar, always a liar,' whenever I caught my cousin stretching the truth.
