The present perfect tense in Spanish is used to talk about recent events. It has two parts: the conjugated form of haber and the past participle of the main verb. For regular verbs, the past participle is formed by adding "ado" to AR verbs and "ido" to ER and IR verbs. There are also some irregular past participles. The present perfect is used with words like ya (already), todavía no (not yet), and nunca (never) to discuss timing.
