Necesitar: Saying What You Need
Necesitar gives practical needs a clear voice. Combine necesito or necesita with travel items, help, food, and other essentials you may genuinely need.
Learning objective
Use necesito and necesita for practical everyday needs.
Necesitar is a verb meaning to need. Use necesito for the speaker: Necesito ayuda means I need help. Use necesita with usted, él, or ella: Usted necesita una reserva means You need a reservation. These present forms describe a practical need now or generally.
The informal tú form is necesitas, nosotros or nosotras uses necesitamos, and ustedes, ellos, or ellas uses necesitan. Necesitar is a regular ar verb, meaning its forms follow the common pattern for infinitives ending in ar. Remove ar and add the ending that matches the subject.
A noun can follow necesitar directly. Necesito agua means I need water, while Necesito un teléfono means I need a phone. Use an article when the noun phrase calls for one; an unmeasured substance such as water often appears without an article in this general request.
An infinitive can also follow: Necesito descansar means I need to rest. Descansar is the unchanged dictionary form meaning to rest. Only necesito changes for the speaker. In an urgent situation, a clear direct statement is useful; in ordinary service, add por favor or an explanation when it helps cooperation.
Examples
Necesito ayuda.
I need help.
Ayuda means help and follows necesito directly.
¿Necesitas agua?
Do you need water?
Necesitas addresses one person informally.
Usted necesita una reserva.
You need a reservation.
Necesita matches respectful singular usted.
Necesito descansar.
I need to rest.
The infinitive descansar remains unchanged after necesito.
Common mistake
- Instead of
- Necesito descanso ahora when the intended meaning is I need to rest now.
- Try
- Necesito descansar ahora.
Descanso can be a noun meaning rest or a verb form meaning I rest, while descansar is the infinitive required after necesito for the intended action. The original may express I need a break or rest in some contexts, so it is not meaningless; it simply does not build the requested verb pattern.
Practice
Try it yourself
Use necesitar to say I need water, you informally need a telephone, and she needs to rest. Identify which sentence has a second verb and keep that verb in its infinitive.
