The Preterite AR Verbs

To conjugate the preterite ( that means past ) AR Spanish verbs you chop off the AR part of the verb and then add the correct ending

here are the endings for the AR verbs:

Yo... é
Tú... aste
Usted... ó

Nosotros... amos
Ustedes....aran

The preterite is the past which makes me think of cemeteries because everyone who is buried there has lives that are in the PAST.

I imagine a grave yard with ghosts making all of these sounds to remind me of the preterite Spanish AR verb endings

Just say this to yourself 100 times, "eee Nasty ooo  amos aron" That should keep it in your head until the day you become a ghost.

 The preterit verb endings for the ER and IR verbs follow a similar pattern:

ER  verbs                                                           Ir verb
yo..í                                                              Yo...í
Tú...iste                                                         Tú...iste
Usted...ió                                                       Usted...ió

Nosotros...imos                                            Nosotros...imos
Ustedes...ieron                                              Ustedes...ieron
