* Combines each given item into a noun series sentence fragment. It does this

* functions.
|
|
*
|
|
* **Examples:**
|
|
*
|
|
* - `["A", "B"] => "A and B"`
|
|
* - `["A", "B", "C"] => "A, B, and C"`
|
|
*
|
|
* **Why only nouns?**
|
|
*
|
|
* Some languages need a bit more context to translate other series.
