Griego y copto
Las letras griegas son los 24 caracteres del alfabeto usado en Grecia durante más de 2,500 años. Hoy aparecen en matemáticas, física, biografías de redes sociales, y nombres de usuario para videojuegos. Aquí puedes copiar cada letra, en mayúscula y minúscula, y entender lo que realmente significa antes de pegarla.
¿Qué son las letras griegas y para qué se usan?
El alfabeto griego tiene 24 letras. Cada una representa un sonido, de la misma manera que nuestro alfabeto. La diferencia es que muchas letras griegas también se usan como símbolos en ciencia, matemáticas, y estadística.
Por ejemplo, la letra pi (π) representa el número 3.14159, usado para calcular el área de un círculo. La letra sigma (Σ) se usa para sumar una serie de números. Estos símbolos son parte del lenguaje técnico en todo el mundo, no solo en países de habla griega.

How to Pronounce Them
Most Greek letters sound close to how they are written. A few common exceptions:
- Χ (chi) sounds like the Spanish j in “jamás,” not like “ch” in English.
- Ξ (xi) sounds like “ksee.”
- Φ (phi) sounds like a soft f.
What Does Each Greek Letter Mean?
These are the Greek letters people search for most, and what they are actually used for.
| Greek Letter | Common Uses |
|---|---|
| Α α Alpha | Represents the first item in a list. In statistics, alpha is the significance level in a test, for example α = 0.05. |
| Β β Beta | In finance, measures how volatile a stock is compared to the market. In physics, it describes beta particles. |
| Γ γ Gamma | Used for gamma rays in physics and for the Euler–Mascheroni constant in mathematics. |
| Δ δ Delta | Uppercase Δ represents a change or difference between two values. Lowercase δ is used for very small changes. |
| Ε ε Epsilon | Represents a very small quantity close to zero in calculus and mathematical analysis. |
| Ζ ζ Zeta | Appears in the Riemann zeta function, a central topic in number theory. |
| Η η Eta | In engineering, represents the efficiency of a machine or process. |
| Θ θ Theta | Almost always used to represent an angle. |
| Ι ι Iota | In everyday speech, “not one iota” means a tiny amount. That phrase comes directly from this letter. |
| Κ κ Kappa | In statistics, measures how much two evaluators agree, known as Cohen’s kappa. |
| Λ λ Lambda | Represents wavelength in physics. In programming, it describes anonymous functions known as lambda functions. |
| Μ μ Mu | Represents the mean in statistics and the “micro” prefix in units of measurement. |
| Ν ν Nu | Used to represent frequency in physics. |
| Ξ ξ Xi | Appears in statistics to name random variables. |
| Ο ο Omicron | One of the least used letters as a symbol outside historical or linguistic contexts. |
| Π π Pi | Represents 3.14159, the ratio between a circle’s diameter and its circumference. |
| Ρ ρ Rho | Represents density in physics and correlation in statistics. |
| Σ σ Sigma | Uppercase Σ means the sum of a series. Lowercase σ represents standard deviation. |
| Τ τ Tau | In physics, describes torque or a characteristic time in a process. |
| Υ υ Upsilon | Less common, appears in some physics formulas. |
| Φ φ Phi | Represents the golden ratio (1.618) and magnetic flux in physics. |
| Χ χ Chi | Used in the chi-squared test, a common tool in statistics. |
| Ψ ψ Psi | Represents the wave function in quantum mechanics. |
| Ω ω Omega | Lowercase ω represents angular velocity in physics. Uppercase Ω is the symbol for the ohm, the unit of electrical resistance. |
