necesitar

neh-seh-see-TAHRne.se.siˈtaɾ

verbA1general
Use this when there's a basic need or requirement, like needing an object or service for personal use or a simple task.
A small, empty blue watering can sits on dry, cracked earth. Above it, a large, friendly gray rain cloud is beginning to pour a single stream of water toward the can's spout, illustrating a requirement.

Examples

Necesito un café antes de empezar a trabajar.

I need a coffee before starting work.

¿Tú necesitas ayuda con ese problema de matemáticas?

Do you need help with that math problem?

El coche necesita mucha gasolina para este viaje.

The car requires a lot of gasoline for this trip.

Needing an Action (Same Subject)

If you need yourself to do something, use 'necesitar' followed directly by the base form of the second verb (the infinitive): 'Necesito estudiar' (I need to study).

Needing Someone Else to Act (Different Subject)

When you need another person to take action, you must use 'que' followed by the special verb form (the subjunctive). The second verb changes form: 'Necesito que estudies' (I need you to study).

Using 'Tener' for Requirement

Mistake: “Tengo dinero (I have money).”

Correction: Necesito dinero (I need money). 'Tener' means 'to possess,' not 'to require.' Only use 'necesitar' when you feel a requirement or lack something.

Incorrect Verb Form After 'Que'

Mistake: “Necesito que tú estudias.”

Correction: Necesito que tú *estudies*. If the subject changes after 'que,' the verb must change to the subjunctive (the special 'e' ending for -ar verbs).

requerir

reh-keh-REERrekeˈɾiɾ

verbB1formal
Use this when something needs or calls for a specific thing, action, or condition to be fulfilled, often in a more formal or technical context.
A chef looking at a table with flour, eggs, and a bowl, needing them to bake.

Examples

Esta planta requiere mucha luz solar.

This plant requires a lot of sunlight.

El trabajo requiere hablar inglés con fluidez.

The job requires speaking English fluently.

Aprender a tocar el piano requiere paciencia.

Learning to play the piano needs patience.

The Stem Change Rule

This verb is a 'boot verb,' meaning the middle 'e' changes to 'ie' in all present tense forms except 'nosotros' and 'vosotros'.

The Hidden 'I' Change

In the past tense (third person) and the special 'wish' form (subjunctive), the 'e' changes to a simple 'i' instead of 'ie'.

Keeping the 'e' in the Gerund

Mistake: “Estoy requeririendo ayuda.”

Correction: Estoy requiriendo ayuda. (The 'e' must change to 'i' in the -iendo form).

exigir

eh-hee-HEEReksiˈxiɾ

verbB2general
Use this when a situation or task demands something specific and often difficult, emphasizing the intensity of the need.
A small sprout in a pot needing water from a watering can to grow.

Examples

Este deporte exige mucho esfuerzo físico.

This sport requires a lot of physical effort.

La situación exige una respuesta inmediata.

The situation calls for an immediate response.

Aprender piano exige paciencia.

Learning piano requires patience.

Inanimate Subjects

Notice how the 'subject' of the sentence is often a thing, not a person (e.g., 'El examen exige...'). This is exactly like saying 'The test requires...' in English.

precisar

pre-see-SARpɾesiˈsaɾ

verbB1formal
Use this when a specific item, action, or piece of information is necessary to complete something, often implying a precise need.
A thirsty traveler in a desert reaching for a glass of clear water.

Examples

Preciso un poco más de información para terminar el informe.

I need a little more information to finish the report.

Las plantas precisan agua y luz solar para crecer.

Plants require water and sunlight to grow.

Este proyecto precisa de una gran inversión inicial.

This project requires a large initial investment.

The 'de' Option

In formal Spanish, you can add the word 'de' after 'precisar' (e.g., 'preciso de tu ayuda'). It means the exact same thing as just saying 'preciso tu ayuda,' but it sounds slightly more professional.

Formal vs. Informal

While 'precisar' and 'necesitar' both mean 'to need,' use 'precisar' for writing essays or business emails, and 'necesitar' when talking to friends.

Using it for everyday needs

Mistake: “Preciso ir al baño.”

Correction: Necesito ir al baño.

demandar

deh-mahn-DAHRdemanˈdaɾ

verbB2formal
Use this when a project, situation, or task calls for significant effort, resources, or attention, implying a substantial demand.
A person carrying a very large, heavy stack of colorful boxes.

Examples

Este proyecto demanda mucho tiempo y esfuerzo.

This project requires a lot of time and effort.

El mercado demanda nuevos productos tecnológicos.

The market demands new technological products.

La situación demanda una respuesta inmediata.

The situation requires an immediate response.

Abstract Subjects

In this sense, the 'thing' doing the demanding is often an abstract concept like 'the job' or 'the situation,' rather than a person.

Demand vs. Exigir

Mistake: “Saying 'demando que te vayas' (I demand that you leave).”

Correction: While understandable, 'exigir' is much more natural for personal commands: 'Exijo que te vayas'.

querer

keh-REHRkeˈɾeɾ

verbB1general
Use this in the impersonal sense ('it requires') to mean 'to try' or 'to attempt' to do something, often implying difficulty or failure.
A determined hiker stands at the beginning of a clear, winding path that leads toward a sunny mountain peak in the distance, symbolizing their purpose.

Examples

Quiso arreglar el coche pero no pudo.

He tried to fix the car but he couldn't.

Este proyecto quiere mucho esfuerzo.

This project requires a lot of effort.

Querían entrar a la fuerza.

They attempted to enter by force.

Past Tense and Attempt

When used in the simple past (preterite: quise, quiso), 'querer' often shifts meaning from 'wanted' to 'tried' or 'attempted,' especially when the outcome was unsuccessful.

Overuse for 'Try'

Mistake: “Quiero probar el nuevo café.”

Correction: Intento probar el nuevo café. (Use 'intentar' or 'tratar de' when the focus is purely on the action of 'trying' something out, not 'wanting' to.)

Confusing 'need' with 'demand' or 'exige'

Learners often use 'demandar' or 'exigir' when a simple 'necesitar' would suffice. Remember that 'demandar' and 'exigir' imply a stronger, more intense need, often involving resources or effort, while 'necesitar' is for everyday, basic needs.
