Article: " Just as in English, you may also have situations where you would use the infinitive in Spanish. For example, the phrase "sin parar" means "without stopping." You also use the infinitive when you combine parar with another verb. For example, "Ella puede parar por mi casa" means "She can stop by my house." Parar is a regular -ar verb. To conjugate Spanish verbs, you must first remove the -ar ending. Then you'll add the appropriate ending to the verb stem par-, depending on the tense, gender, and number of people doing the stopping. In Spanish, the present tense is not just used for things currently happening. You'll also use the present tense to talk about habitual actions or things taking place in the immediate future. For example, you might say "para el carro," or "stop the car."   Yo paro: I stop.  Tú paras: You stop.  Él/ella/usted para: He/she stops; you stop.  Nosotros/-as paramos: We stop.  Vosotros/-as paráis: You all stop.  Ellos/ellas/ustedes paran: They/you all stop. Spanish speakers typically use the imperfect tense when talking about something that was previously happening before an interruption. This tense is also used for past habitual actions. For example, you might say "Parábamos el carro para un gato para cruzar la calle," or "We were stopping the car for a cat to cross the street."   Yo paraba: I was stopping.  Tú parabas: You were stopping.  Él/ella/usted paraba: He/she was stopping; you were stopping.  Nosotros/-as parábamos: We were stopping.  Vosotros/-as parabais: You all were stopping.  Ellos/ellas/ustedes paraban: They/you all were stopping. Anytime you're referring to something that happened entirely in the past, you want to use the preterite tense. For example, you might say "Él paró su carro en el cruce," or "He stopped his car at the intersection."   Yo paré: I stopped.  Tú paraste: You stopped.  Él/ella/usted paró: He/she/you stopped.  Nosotros/-as paramos: We stopped.  Vosotros/-as parasteis: You all stopped.  Ellos/ellas/ustedes pararon: They/you all stopped. Unlike English, the simple future tense in Spanish is just one word. Use this tense if you want to talk about something that will happen further off in the future. For example, you might say "Pararé el carro para desayunar," or "I will stop the car for breakfast."   Yo pararé: I will stop.  Tú pararás: You will stop.  Él/ella/usted parará: He/she/you will stop.  Nosotros/-as pararemos: We will stop.  Vosotros/-as pararéis: You all will stop.  Ellos/ellas/ustedes pararán: They/you all will stop.
