The Myers Briggs letters meaning is the foundation of the world-famous Myers-Briggs Type Indicator (MBTI) — a psychological model that categorizes personality into 16 unique types. Each MBTI type is represented by a combination of four letters, such as INTJ, ESFP, or ENFP. But what do these letters really mean?

In this article, we’ll explain the full Myers Briggs letters meaning, break down each dimension, and help you understand how the letters combine to form your personality type.

What Do the Myers Briggs Letters Stand For?

The Myers Briggs letters represent four key aspects of personality. Each letter describes how you focus your energy, process information, make decisions, and organize your life. Here’s a quick overview:

  • E or I – Extraversion vs. Introversion
  • S or N – Sensing vs. Intuition
  • T or F – Thinking vs. Feeling
  • J or P – Judging vs. Perceiving

Each person’s type is made up of one letter from each pair, resulting in a four-letter combination — for example, INFJ, ESTP, or INTP. Let’s explore the meaning of each Myers Briggs letter in detail.

1. Extraversion (E) vs. Introversion (I)

The first letter in your Myers-Briggs type represents how you gain and direct your energy.

  • Extraversion (E): You gain energy from being around people and engaging in activities. Extraverts are outgoing, talkative, and thrive in social environments.
  • Introversion (I): You recharge through solitude and reflection. Introverts prefer smaller groups, deep conversations, and quiet settings.

Example: An ENTJ tends to be expressive and assertive, while an INTJ prefers calm focus and introspection.

2. Sensing (S) vs. Intuition (N)

The second letter describes how you gather and interpret information about the world.

  • Sensing (S): You focus on facts, details, and practical information. Sensors prefer concrete data and real-world experiences.
  • Intuition (N): You look for patterns, possibilities, and abstract ideas. Intuitive types are imaginative and future-oriented thinkers.

Example: A ISTJ relies on facts and experience, while an INFJ often looks for deeper meanings and long-term implications.

3. Thinking (T) vs. Feeling (F)

The third letter reveals how you make decisions and evaluate situations.

  • Thinking (T): You prioritize logic, consistency, and objectivity. Thinkers value fairness and truth over personal emotions.
  • Feeling (F): You base decisions on empathy, harmony, and personal values. Feelers prioritize maintaining relationships and emotional understanding.

Example: An INTP might make a decision based on analysis, while an INFP considers how that decision affects others emotionally.

4. Judging (J) vs. Perceiving (P)

The fourth letter explains how you approach the outside world and handle structure.

  • Judging (J): You prefer order, planning, and structure. Judging types like to make decisions early and follow schedules.
  • Perceiving (P): You value flexibility, adaptability, and spontaneity. Perceiving types enjoy keeping their options open.

Example: An ENFJ prefers a well-organized plan, while an ENFP thrives in a spontaneous and dynamic environment.
