The Myer Briggs letter meaning helps decode the four-letter personality codes used in the Myers-Briggs Type Indicator (MBTI), one of the most popular personality systems in the world. Each letter in a person’s MBTI type — such as INFJ, ESTP, or ENFP — represents a psychological preference that shapes how you perceive the world, make decisions, and interact with others. Understanding what these letters mean can give you valuable insights into your behavior, relationships, and career strengths.
What Are the Myer Briggs Letters?
Every MBTI personality type is made up of four letters. The Myer Briggs letter meaning comes from four key dichotomies (opposites) that describe fundamental aspects of your personality:
- E or I – Extraversion or Introversion
- S or N – Sensing or Intuition
- T or F – Thinking or Feeling
- J or P – Judging or Perceiving
By combining one letter from each of these four pairs, you get your unique personality code — for example, INTJ (Introverted, Intuitive, Thinking, Judging) or ESFP (Extraverted, Sensing, Feeling, Perceiving). The meaning of each letter reveals how you process information, make decisions, and prefer to live your life.
The Four Myer Briggs Letter Meanings Explained
1. E or I – Extraversion vs. Introversion
The first letter in your type describes where you focus your energy and how you recharge:
- E – Extraversion: Extraverts draw energy from social interaction and external stimulation. They enjoy conversation, collaboration, and active environments.
- I – Introversion: Introverts recharge through solitude and reflection. They prefer deep, meaningful interactions and quiet environments over large groups.
Example: An ENFP thrives in group discussions, while an INFP may prefer to process ideas internally before sharing them.
2. S or N – Sensing vs. Intuition
The second letter represents how you take in and process information:
- S – Sensing: Sensors focus on facts, details, and what can be observed directly. They trust experience and prefer practical, realistic information.
- N – Intuition: Intuitives look for patterns, meanings, and future possibilities. They rely on imagination and enjoy abstract or conceptual thinking.
Example: A ISTJ (Sensing) values concrete data and proven methods, while an ENTP (Intuitive) enjoys exploring innovative ideas and possibilities.
3. T or F – Thinking vs. Feeling
The third letter in the Myer Briggs letter meaning shows how you make decisions and evaluate situations:
- T – Thinking: Thinkers prioritize logic, fairness, and objectivity. They prefer to base decisions on facts rather than emotions.
- F – Feeling: Feelers prioritize empathy, values, and personal connection. They often make decisions based on how outcomes will affect people emotionally.
Example: A ENTJ (Thinking) may focus on efficiency and results, while an ESFJ (Feeling) considers the emotional well-being of everyone involved.
4. J or P – Judging vs. Perceiving
The fourth and final letter in the Myer Briggs letter meaning reflects how you approach structure, organization, and daily life:
- J – Judging: Judging types prefer order, planning, and clear decisions. They enjoy structure and like to have a sense of control over their environment.
- P – Perceiving: Perceiving types are flexible, adaptable, and open-minded. They prefer spontaneity and enjoy exploring new options before committing.
Example: An INFJ (Judging) plans ahead and values predictability, while an INFP (Perceiving) prefers to stay open to new possibilities and adjust as they go.
