conociesen

Conociesen is a verb form in Spanish, specifically the imperfect subjunctive mood. It represents the third-person plural form of conocer in the imperfect subjunctive, used in subordinate clauses that require the subjunctive and in hypothetical or past-context situations.

Morphology and variants: The imperfect subjunctive has two parallel endings. The form conociesen belongs to the -se variant, while conocieran is the corresponding -ra variant. Other persons and numbers follow the same two-pattern system: conociese, conocieses, conociese, conociésemos, conocieseis, conociesen; or the -ra equivalents such as conociera, conocieras, conociera, conociéremos, conocierais, conocieran. Both sets are correct and largely interchangeable, though regional and stylistic preferences vary.

Usage: Conociesen is used in subordinate clauses after expressions that trigger the subjunctive, such as doubt, emotion, possibility, or unreality, and in certain conditional or hypothetical contexts. Examples: “No creían que ellos conociesen al nuevo vecino.” (They didn’t believe that they knew the new neighbor.) “Si ellos conociesen el camino, llegarían más rápido.” (If they knew the way, they would arrive faster.) The imperfect subjunctive often appears after past-tense main clauses or in reported speech.

Etymology and context: The form derives from the Spanish verb conocer, itself from Latin cognoscere. The imperfect subjunctive mood preserves a past-sequence meaning and is an essential tool for expressing hypothetical, uncertain, or non-realized actions in the past.
