Express a strong inference with tener que

Tener que can express a conclusion that the evidence makes highly compelling, not only external obligation. A stative or perfect infinitive and an evidence-rich context often favor the inferential reading.

Con todas las ventanas cerradas, el ruido tiene que venir del piso de arriba.
With all the windows closed, the noise has to be coming from upstairs.The circumstances support a strong deduction rather than imposing a duty on the noise.

Present an approximate or summarizing conclusion

Venir a plus infinitive can qualify an equivalence, amount, or final interpretation. It often means roughly, essentially, or in the end, allowing a speaker to summarize without claiming exact identity.

La reforma viene a reconocer un derecho que ya existía en la práctica.
The reform essentially recognizes a right that already existed in practice.Viene a reconocer presents the reform's approximate or summarizing effect.

Common mistakes

Puede que el conductor haber tomado otra ruta.

Puede que el conductor haya tomado otra ruta.

Puede que requires a finite subjunctive clause, not an infinitive.

Tiene que haber salido means obligation in every context.

With evidence such as an empty office, tiene que haber salido can express a strong inference.

Lexical meaning and discourse context distinguish deduction from obligation.

Viene a costar cien euros means someone physically comes to charge exactly €100.

Viene a costar cien euros can mean it costs roughly €100.

The periphrastic meaning is approximate; context determines whether venir keeps literal movement.
