Past Participle or Adjective?
In the past, many verbs in Spanish had two past participle forms: a regular form and an irregular form. Nowadays, the irregular forms are no longer considered past participles, but simply adjectives.
A few examples of these tricky pairs are shown in the table below. Keep in mind that only the forms in the "Past Participle" column in the table below can be used in compound tenses, such as the present perfect.
Infinitive Adjective Past Participle
atender
atento
atendido
bendecir
bendito
bendecido
confundir

corromper

corrompido
despertar

maldecir

poseer
poseso
poseído
presumir
presunto
presumido
suspender

The first example below shows the past participle of despertar being used in the present perfect, while the second example shows an adjective form related to despertar.
¿Has despertado a tu mamá?
Have you awoken your mother?
Los niños están despiertos.
The children are awake.
According to the Real Academia Española, only three verbs have two acceptable past participle forms, both of which can be used in perfect tenses.
