Spanish/Tenses/Indicative/Simple/Preterite

Some things to note:
 * 1) Most significantly, the -ER and -IR verbs have exactly the same endings. This makes learning the preterite simpler.
 * 2) The nosotros forms of the -AR and -IR verbs appear exactly the same as they do in the present. You must figure out their meaning based on context.
 * 3) Accent marks are essential. Hablo and Habló are completely different; an accent mark makes the difference between "I speak" and "he spoke."
