PresentProgressive

The present progressive is formed with a conjugated form of the verb //estar// followed by a present participle, the equivalent of an "-ing" word in English.

Estar is conjugated as follows:
 * **Yo estoy** || **Nosotros estamos** ||
 * **Tú estás** || **Vosotros estáis** ||
 * **Usted está** || **Ustedes están** ||
 * **Él está** || **Ellos están** ||
 * **Ella está** || **Ellas están** ||

The present participle is formed as follows:


 * - ar** verbs, the ending changes to **-ando**
 * -er** and **-ir** verbs, the ending changes to **-iendo**

Verbs do NOT stem-change in the present participle form except for a select few stem-changing **-ir** verbs that include the following:
 * //**pedir**// || **pidiendo** ||
 * //**servir**// || **sirviendo** ||
 * //**morir**// || **muriendo** ||
 * //**dormir**// || **durmiendo** ||
 * //**decir**// || **diciendo** ||

Other exceptions include verbs that have three vowels in a row when in the present participle form. To avoid this awkward construction, the "i" in "iendo" becomes "y": An exception to this rule is the stem-changing //**seguir**//, which becomes **siguiendo**.
 * //**caer**// || **cayendo** ||
 * //**creer**// || **creyendo** ||
 * //**leer**// || **leyendo** ||
 * //**traer**// || **trayendo** ||
