Contenían is a Spanish verb, the imperfect indicative form of the verb contener. It translates to "they contained," "you all contained," or "it contained" depending on the context and the subject of the sentence. The imperfect tense in Spanish is used to describe ongoing actions or states of being in the past, as well as habitual actions or descriptions in the past.
