A1 (Beginner)Lesson 5: Irregular & Modal Verbs
Poder (can/to be able), querer (to want), and precisar (to need) are the three most essential modal verbs in Portuguese, used constantly to express ability, desire, and necessity in everyday communication.
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 can be followed by an infinitive: Posso ajudar, Quero viajar, Preciso trabalhar. After precisar, de before the infinitive is optional.
Only precisar adds de before a noun: Preciso de ajuda.
Poder (eu posso) and querer (você/ele/ela quer) are irregular; precisar is regular.
poder / querer / precisar (conjugated) + infinitive — and precisar + de + noun

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.
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). Poder and querer are irregular; precisar follows the regular –AR pattern.
