penetrasteis

Penetrasteis is the second-person plural form of the Spanish verb penetrar in the pretérito indefinido (simple past). It corresponds to “you all penetrated” and is used primarily in Spain, where the vosotros form is common. In Latin American Spanish, the past tense for ustedes is penetraron, and the vosotros form is rarely used in everyday speech.

Penetrar is a transitive verb meaning to go through, to enter through a barrier, or to breach a barrier. Its uses can be literal, as in penetrating a wall or defenses, or metaphorical, such as penetrating defenses, penetrando a deeper layer of a problem, or penetrating information through investigation. The meaning can range from physical entry to a figurative breakthrough.

Grammatical notes: penetrasteis is one of the vosotros past forms. Related forms include penetrating (present) penetráis; imperfect penetrabais; future penetraréis; past participle penetrado. The verb derives from Latin penetrare, formed with the prefix pene- linked to the root -trar, and follows regular -ar conjugation patterns in all tenses for -ar verbs.

Examples:

- Ayer penetrasteis las defensas del castillo.

- Con esa táctica, penetrasteis la resistencia enemiga.

- La investigación penetró las capas de la verdad.

Penetrasteis thus appears in narrative or descriptive contexts that employ the vosotros form, though in many Spanish-speaking regions it is often replaced by ustedes in the past tense.
