 * **Hierarchical** — represents hierarchical data structures, such as JSON or a tree of JVM objects.
 * **Functional** — data processing pipeline is organized in a chain of `DataFrame` transformation operations. Every operation returns a new instance of `DataFrame` reusing underlying storage wherever it's possible.
 * **Readable** — data transformation operations are defined in DSL close to natural language.
-* **Practical** — provides simple solutions for common problems and ability to perform complex tasks.
+* **Practical** — provides simple solutions for common problems and the ability to perform complex tasks.
 * **Minimalistic** — simple, yet powerful data model of three column kinds.
 * **Interoperable** — convertable with Kotlin data classes and collections.
 * **Generic** — can store objects of any type, not only numbers or strings.
