Conjugate irregular verbs ending in -zar in el Pretérito Indefinido (simple past)

Verbs ending in-zar like: organizar (to organise), analizar (to analyse), cazar (to hunt) are irregular in El Pretérito Indefinido because the spelling changes for pronunciation reasons in the first person singular (yo).

yo organicé
organizaste
él / ella / Ud. organizó
nosotros / nosotras  organizamos
vosotros / vosotras  organizasteis
ellos / ellas / Uds. organizaron
Notice that the -z- is replaced with -c-. However, apart from the yo form, all the other endings are the same as those of regular -ar verbs: -aste, -o, -amos, -asteis, -aron.
