Sure, here is a SQL query that will return the number of unique salespeople from the "orders" table:

```sql
SELECT COUNT(DISTINCT salesperson) AS unique_salespeople
FROM orders;
```

Here's a step-by-step breakdown of the query:

1. `SELECT`: This keyword is used to select data from a database.

2. `COUNT(DISTINCT salesperson)`: The `COUNT` function is used to count the number of rows that match a specified condition. The `DISTINCT` keyword is used in conjunction with `COUNT` to count only unique values, in this case, unique salespeople.

3. `AS unique_salespeople`: The `AS` keyword is used to rename a column or table with an alias. Here, it's used to rename the count of unique salespeople as "unique_salespeople".

4. `FROM orders`: The `FROM` keyword is used to specify the table from which to select the data, in this case, the "orders" table.
