precisais

Precisas is a conjugated form of the Portuguese verb precisar, meaning to need or to require. Precisar is a regular -ar verb, and precisas, precisas, precisa, precisamos, precisais, precisam are its present indicative endings. In particular, precisais corresponds to the second-person plural form (you all need) when using the pronoun vós.

Usage notes:

In contemporary Brazilian Portuguese, the second-person plural is typically expressed with vocês precisam, and precisais is rarely used outside traditional or regional European Portuguese contexts. In contrast, European Portuguese commonly employs vós precisais in formal or literary registers, though even there, it is increasingly replaced by vocês precisam in everyday speech.

Examples:

- Vós precisais de mais tempo para completar o projeto. (You all need more time to complete the project.)

- Vós não precisais de ajuda agora. (You all do not need help right now.)

In modern practice, the corresponding Brazilian Portuguese form would be: Vocês precisam de mais tempo.

Grammatical notes:

Precisar, and thus precisais, appear in several tenses and moods. The present subjunctive second-person plural is preciseis (spelled preciseis in some varieties), which can cause confusion due to similarities with the indicative form. The distinction between vós and vocês as subject pronouns affects which form is standard in a given variety of Portuguese.

Summary:

Precisas is a non-lexical item in its own right but functions as a plural verb form. It illustrates the divergence between European Portuguese usage (which may still employ vós precisais) and Brazilian Portuguese practice (which uses vocês precisam).
