Impusiste

Impusiste is the second-person singular form of the Spanish verb imponer in the pretérito perfecto simple (simple past). It denotes that you imposed something on someone or on a group in the past, such as a rule, a tax, a burden, or a measure. The form is used in narrative or descriptive contexts to indicate agency by the subject you.

Conjugation notes:

- Pretérito perfecto simple (tú): impusiste

- Other key forms in the same tense include: impuse (yo), impuso (él/ella/usted), impusimos (nosotros), impusisteis (vosotros), impusieron (ellos/ellas/ustedes)

- The infinitive is imponer; related participle is impuesto.

Etymology and meaning:

Imponer derives from Latin imponere, composed of prefix im- (upon) and ponere (to place, to set). In Spanish, imponer covers the act of placing an obligation, burden, duty, rule, or sanction upon someone else, often in formal or institutional contexts.

Usage and nuance:

Imponer is used when an authority or entity compels others to accept or follow something. It can refer to tangible impositions (un impuesto, una carga) or abstract measures (reglas, normas). While impusiste specifically points to the past act by you of imposing, similar forms like impusieron or impuso describe actions by others or by third persons in different subjects.

Examples:

- El gobierno impuso un nuevo impuesto. (The government imposed a new tax.)

- Tú impusiste condiciones estrictas para la negociación. (You imposed strict conditions for the negotiation.)

- La escuela impuso un reglamento para el uso de dispositivos. (The school imposed a regulation for device use.)
