prescreves

Prescreves is the second-person singular present indicative form of the Portuguese verb prescrever. It is used with the informal subject pronoun tu, and means “you prescribe.” The most common sense concerns writing a medical prescription or ordering a course of treatment, but the verb can also mean to lay down rules, guidelines, or conditions in advance.

Etymology and scope: prescrever derives from Latin praescribere, “to write beforehand.” The related noun prescrição denotes the act or document of prescribing; in medicine this is the prescription (receita médica). In legal contexts, prescrição can also mean a statute of limitations or the lapse of a right.

Conjugation and usage: Present tense forms include eu prescrevo, tu prescreves, ele prescreve, nós prescrevemos, vós prescreveis, eles prescrevem. In Brazilian Portuguese, the second-person singular tu is regional; standard usage often employs você prescreve (“you prescribe”). Example: Tu prescreves um analgésico para aliviar a dor.

Note: The topic intersects linguistics and regional variation, reflecting differences in pronoun use and verb conjugation between European Portuguese and Brazilian Portuguese. The term prescrição is closely related and commonly used in medical contexts, while prescrever and its forms are primarily encountered in everyday and professional language related to medicine and rule-setting.
