Essential modals: poder, querer, precisar

• Poder (can / may): posso, pode, podemos, podem — ability, permission, possibility.

• Querer (to want): quero, quer, queremos, querem — desires and wishes.

• Precisar (to need): preciso, precisa, precisamos, precisam — necessity.

• All three take a plain infinitive: Posso ajudar, Quero viajar, Preciso trabalhar.

• Only precisar adds de before a noun: Preciso de ajuda.

• Poder is irregular (eu posso); querer and precisar are regular — just note the short você/ele/ela form quer.

These three verbs turn a plain statement into what you can, want, or need to do — the backbone of everyday Brazilian conversation. With them you can ask permission (Posso entrar? — May I come in?), order politely (Quero um café — I want a coffee) and state a need (Preciso de ajuda — I need help). Best of all, they pair with the infinitives you already know: posso, quero or preciso + almost any verb. Learn these three and you instantly multiply what you can say.

Three everyday helper verbs

Poder (can / may), querer (to want) and precisar (to need) are modal verbs: you conjugate them and add a second verb in the infinitive — its dictionary form (–ar, –er, –ir). Only poder is irregular; the other two follow patterns you already know.
