How to Say "to need" in Spanish
The most common Spanish word for “to need” is “necesitar” — use 'necesitar' when you have a general requirement or desire for something or someone.
necesitar
neh-seh-see-TAHRne.se.siˈtaɾ
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).
faltar
fal-TARfalˈtaɾ
Examples
Me falta un calcetín.
I am missing a sock.
Nos falta sal para la sopa.
We lack salt for the soup.
Faltan tres sillas en el salón.
Three chairs are missing from the living room.
The 'Gustar' Structure
This verb often works 'backwards'. Instead of saying 'I lack sugar', you say 'Sugar is lacking to me' (Me falta azúcar).
Plural Matching
The verb changes based on the things that are missing. If one thing is missing, use 'falta'. If two or more are missing, use 'faltan'.
Using 'Yo' instead of 'Me'
Mistake: “Yo falto dinero.”
Correction: Me falta dinero. (Think of it as 'Money is missing to me'.)
precisar
pre-see-SARpɾesiˈsaɾ
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.
requerir
reh-keh-REERrekeˈɾiɾ
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).
