Grammar Rules of "ing" Words
When speaking English, to change from play to playing, you add "ING." To change swim to swimming, you add another m as well as "ING." The rules vary.
For Spanish, what specific rules are there as far as "ING words" are concerned?
You don't need to include exceptions.

In Spanish there are regular and irregular verbs. According to the ending or the verb, there is a possible ending to add (replacing the endings 'ar', 'er', ir') in order to get the gerund:
- AR --> ando. Amar --> Amando.
- ER --> iendo. Comer --> Comiendo.
- IR --> iendo. Vivir --> Viviendo.
However there are other irregular verbs where also the stem changes. You can read more about this here.
In English you add ing to a verb and you can use that word as a noun. Don't do that in Spanish. In Spanish that noun will be the infinitive version of the verb. Example:
Walking is good for the health. / Caminar es bueno para la salud.
One way is using the gerund (gerundio)
For example:
I am playing. Estoy jugando.
Another way is to use the infinitive form: infinitivo
Bailar tango es difícil.
Dancing the tango is hard.

I am not an expert but Spanish has more than on way of dealing with the progresive.
Nado means I swim and I am swimming.
Estoy nadando means I am swimming.
Voy a nadar means I will be swimming.
