Greek Letters in Markdown
Markdown doesn’t natively support Greek letters, but you can use HTML entities and LaTeX syntax to display them. HTML entities like `α` show as α, while LaTeX syntax like `$$\alpha$$` also renders α. Combining these methods provides flexibility across different Markdown parsers.

Markdown is a lightweight markup language widely used for writing documents, README files, and blog posts. While Markdown itself does not directly support Greek letters, there are techniques and extensions that can be used to display them. This article will detail how to use Greek letters in Markdown, covering both basic methods and advanced techniques.
Basic Method: Using HTML Entities
Markdown allows embedding HTML, which means HTML entity codes can be used to display Greek letters. HTML entities are character encodings that start with & and end with ;. Here are some commonly used Greek letters and their corresponding HTML entities:
| Greek Letter | HTML Entity | Example |
|---|---|---|
| α | α |
α (α) |
| β | β |
β (β) |
| γ | γ |
γ (γ) |
| δ | δ |
δ (δ) |
| ε | ε |
ε (ε) |
| θ | θ |
θ (θ) |
| λ | λ |
λ (λ) |
| μ | μ |
μ (μ) |
| π | π |
π (π) |
| σ | σ |
σ (σ) |
| φ | φ |
φ (φ) |
| ψ | ψ |
ψ (ψ) |
| ω | ω |
ω (ω) |
In Markdown, you can directly use these HTML entities to insert Greek letters. For example:
α, β, γ, δ, ε, θ, λ, μ, π, σ, φ, ψ, ω
This will render as: α, β, γ, δ, ε, θ, λ, μ, π, σ, φ, ψ, ω
Advanced Method: Using LaTeX Syntax
If you need to write mathematical formulas or require more complex typesetting in Markdown, you can use LaTeX syntax. Many Markdown parsers (such as Jupyter Notebook and GitHub’s Markdown parser) support LaTeX syntax. LaTeX can be represented using double dollar signs $$.
Here are some commonly used Greek letters and their LaTeX representations:
| Greek Letter | LaTeX Syntax | Example |
|---|---|---|
| α | \alpha |
$\alpha$ |
| β | \beta |
$\beta$ |
| γ | \gamma |
$\gamma$ |
| δ | \delta |
$\delta$ |
| ε | \epsilon |
$\epsilon$ |
| θ | \theta |
$\theta$ |
| λ | \lambda |
$\lambda$ |
| μ | \mu |
$\mu$ |
| π | \pi |
$\pi$ |
| σ | \sigma |
$\sigma$ |
| φ | \phi |
$\phi$ |
| ψ | \psi |
$\psi$ |
| ω | \omega |
$\omega$ |
For example, to use LaTeX to represent Greek letters in Markdown:
$$\alpha, \beta, \gamma, \delta, \epsilon, \theta, \lambda, \mu, \pi, \sigma, \phi, \psi, \omega$$
This will render as: $\alpha, \beta, \gamma, \delta, \epsilon, \theta, \lambda, \mu, \pi, \sigma, \phi, \psi, \omega$
Combining HTML and LaTeX
In some Markdown editors, you can use both HTML entities and LaTeX syntax to flexibly display Greek letters. For example, in GitHub’s Markdown parser, you can use both methods in the same text:
HTML Entities: α, β, γ, δ, ε, θ, λ, μ, π, σ, φ, ψ, ω
LaTeX Syntax: $$\alpha, \beta, \gamma, \delta, \epsilon, \theta, \lambda, \mu, \pi, \sigma, \phi, \psi, \omega$$
Summary
With these methods, you can easily use Greek letters in Markdown documents. Whether using HTML entities or LaTeX syntax, both approaches can meet most needs. When choosing a method, consider the specific use case and the Markdown parser's support.
