Known in Spanish as "el pretérito pluscuamperfecto", the pluperfect tense consists of a verbal tense whose objective is to give knowledge about a topic, fact or event that occurred or was true at a certain time in the past. When we have a conversation based on past events, it is common to use "había" accompanied by a past participle, such as "comido, reído and jugado" to meet the standards of this verb tense.
