What Tense is Hubiera Sido?
Hubiera sido is in the Past Perfect Subjunctive tense in Spanish. This complex verbal form is used to express hypothetical or counterfactual situations in the past, as well as regret, wishes, or emotions related to past events that did not occur.
Understanding the Past Perfect Subjunctive
The Past Perfect Subjunctive (also known as the Pluperfect Subjunctive) is a compound tense, meaning it is formed using an auxiliary verb and a past participle. It allows speakers to delve into hypothetical scenarios that happened—or didn't happen—in the past.
Formation
This tense is constructed by combining the imperfect subjunctive of the auxiliary verb haber with the past participle of the main verb.

Imperfect Subjunctive of Haber: The auxiliary verb haber is conjugated in its imperfect subjunctive form. It has two common sets of endings, both equally valid: one ending in -ra and the other in -se.
Subject Pronoun Imperfect Subjunctive of Haber (Form 1) Imperfect Subjunctive of Haber (Form 2) Yo hubiera hubiese Tú hubieras hubieses Él/Ella/Usted hubiera hubiese Nosotros/as hubiéramos hubiésemos Vosotros/as hubierais hubieseis Ellos/Ellas/Ustedes hubieran hubiesen -
Past Participle: The main verb (in this case, ser) is used in its past participle form. For ser, the past participle is sido. It's important to remember that past participles that form perfect tenses are generally masculine and singular in their base form (though sido remains invariable).
Therefore, hubiera sido is formed by hubiera (imperfect subjunctive of haber) + sido (past participle of ser).
The Role of Ser
In the phrase hubiera sido, the verb ser (to be) is the main verb. The combination specifically means "had been" in a hypothetical past context. For instance, depending on the subject, hubiera sido can translate to "I had been," as in the example hubiera sido meaning "I had been."
