pertenecías

Pertenecías is the imperfect indicative form of the Spanish verb pertenecer for the second person singular, used to indicate that you belonged or used to belong to a group, organization, or category in the past. It is not a noun; the corresponding noun is pertenencia, whose plural is pertenencias, meaning belongings or possessions.

Etymology: pertenecer comes from Latin pertinere "to pertain, to belong" (per- + tenere). The verb follows regular -er conjugation patterns in the imperfect: tú pertenecías, él pertenecía, etc.

Usage: The form appears in narrative or descriptive past contexts. Example: "Cuando era adolescente, tú pertenecías al club de ajedrez." Question form: "¿A qué club pertenecías?" The imperfect tense often conveys habitual membership or a state in the past rather than a completed action.

Distinction: The confusion with the noun "pertenecías" should be avoided; the common noun is "pertenencias," meaning someone's belongings. "Pertenecías" as a word is strictly a verb form.
