Preciso ler isso?
Meaning

✦Grammar Breakdown
Precisolerisso?
Preciso (verbo precisar)
First‑person singular present of precisar used as a modal meaning ‘need to / have to’. It is followed directly by an infinitive without ‘de’.
ler (infinitivo)
The infinitive form of the verb ‘to read’. After modal verbs like precisar, querer, poder, etc., the infinitive stays unchanged.
isso (pronome demonstrativo)
Demonstrative pronoun meaning ‘this’. It refers to something just mentioned or physically present.
Interrogative intonation
In spoken Portuguese a rising intonation turns the statement into a question; written Portuguese adds the opening ‘?’ and closing ‘?’.

✕Common Mistakes
Preciso de ler isso?
The verb precisar does not take the preposition de when followed by an infinitive.
Preciso ler isso.
Without the question marks or rising intonation it becomes a statement: ‘I need to read this.’
Preciso ler isso, eu?
Adding ‘eu’ after the verb is redundant; the subject is already implied by the verb ending ‑o.

Cultural Tip
In Brazil, speakers often replace ‘preciso ler isso?’ with the more colloquial ‘tem que ler isso?’ or ‘preciso ler isso, né?’. Remember that ‘preciso’ can also be an adjective meaning ‘I am precise’; the meaning is clarified by the infinitive that follows. In formal writing, keep the modal verb directly before the infinitive without the preposition ‘de’.
