aparecer

To appear or show up — physically (in a place), visually (in a photo, on a list), or suddenly and unexpectedly (a problem, a memory). One of the most common Spanish verbs, and irregular in the yo form of the present (aparezco) and throughout the preterite (apareció).

• Su nombre no aparece en la lista. — Her name doesn't appear on the list.
• El gato desapareció y apareció tres días después. — The cat vanished and turned up three days later.
• De repente aparecieron nuevas dudas sobre el proyecto. — Suddenly new doubts about the project arose.

Misconjugating the present-tense yo form as *aparo instead of aparezco — like conocer and parecer, aparecer takes the -zco irregular pattern in the first-person singular present.

Often confused with desaparecer.
