Necesitar Conjugation: Preterite & Subjunctive

Instructor: Elena Sacramento Lechado

Elena teaches Spanish as a foreign language and has a PhD in linguistics.

The Spanish verb 'necesitar' means 'to need.' In this lesson, you'll learn how to talk about past actions with its preterite, and how to express doubt or talk about possibilities with its present subjunctive.

Talking About What We Need

Let's say that your Spanish-speaking friend, Carmen, is giving you instructions to prepare a typical dish from her country. You ask her if the amount of ingredients you're using is enough. She might say 'You'll probably need more eggs,' or 'I don't think you need more sugar.' The following day, you tell another friend that you needed Carmen's help, but you managed to prepare a delicious meal.

To talk about these situations in Spanish, we have to use the verb necesitar (pronounced: neh-seh-see-TAHR), which means 'to need.' When Carmen expresses her opinions, or talks about possibilities, she uses the present subjunctive. To talk about what happened yesterday you'd use the preterite. In the following sections, we'll look at these two tenses using plenty of examples. Let's start!

Preterite of Necesitar

We use the preterite to talk about finished actions in the past. So if you want to say that you needed some tips to prepare a dish or that your brother needed help with his exam, use the preterite of necesitar.

The good news is that necesitar is a regular verb, so its conjugation is pretty simple. Just take its stem necesit- and add the endings below.

Note: Pay attention to the forms that require an accent mark (´). In Spanish, it's very important to write them down to avoid confusion with other verbal tenses.
