+title: Truthy and falsy
+description: An overview of boolean logic in the Liquid template language.
+---
+
+In programming, anything that returns `true` in a conditional is called **truthy**. Anything that returns `false` in a conditional is called **falsy**. All object types can be described as either truthy or falsy.

+
+## Truthy
+
+All values in Liquid are truthy except `nil` and `false`.
+
+In the example below, the string "Tobi" is not a boolean, but it is truthy in a conditional:
+
+```liquid
+{% raw %}
+{% assign tobi = "Tobi" %}
+
+{% if tobi %}
+  This condition will always be true.
+{% endif %}
+{% endraw %}
+```
+
+[Strings]({{ "/basics/types/#string" | prepend: site.baseurl }}), even when empty, are truthy. The example below will result in empty HTML tags if `settings.fp_heading` is empty:
+
+<p class="code-label">Input</p>
+```liquid
+{% raw %}
+{% if settings.fp_heading %}
+  <h1>{{ settings.fp_heading }}</h1>
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```html
+<h1></h1>
+```
+
+## Falsy
+
+The falsy values in Liquid are [`nil`]({{ "/basics/types/#nil" | prepend: site.baseurl }}) and [`false`]({{ "/basics/types/#boolean" | prepend: site.baseurl }}).
+
+## Summary
