 Under the hood, the config is parsed into a dictionary. It's divided into
 sections and subsections, indicated by the square brackets and dot notation. For
-example, `[training]` is a section and `[training.batch_size]` a subsections.
+example, `[training]` is a section and `[training.batch_size]` a subsection.
 Subsections can define values, just like a dictionary, or use the `@` syntax to
 refer to [registered functions](#config-functions). This allows the config to
 not just define static settings, but also construct objects like architectures,
