Questions & Answers about Si no oyes el timbre, te mando un mensaje.

Why is it oyes and not oigas after si?

• After si in real, likely conditions, Spanish uses the present indicative, not the subjunctive: Si no oyes...
• Use the imperfect subjunctive only for hypothetical/unreal conditions: Si no oyeras el timbre, te mandaría un mensaje.
• For past, contrary-to-fact: Si no hubieras oído el timbre, te habría mandado un mensaje.

Why is it te mando (present) instead of te mandaré (future)?

• Spanish often uses the present to refer to the future in conditional contexts.
• Te mandaré is also correct but sounds more formal or like a firm promise. Te mando is more casual/immediate.
• All of these are fine, with slight nuance: Si no oyes..., te mando/te mandaré/te voy a mandar...

Can I use escuchas instead of oyes? What’s the difference between oír and escuchar?

• oír = to hear (perceive sound, involuntary); escuchar = to listen (pay attention, intentional).
• Si no oyes el timbre is neutral: you simply don’t hear it. Si no escuchas el timbre suggests you aren’t paying attention.
• Both appear in everyday speech; oír is more precise here.
