Learn Farsi: او مخابره کرد که سیگنال آنجا واضح است. - He transmitted that the signal there is clear.

In Farsi reported speech, you keep the exact tense the original speaker used. The person originally reported, "The signal is clear," so Farsi keeps the present tense است. English shifts tenses to match the past-tense reporting verb ("He transmitted that the signal was clear"), but Farsi retains the original tense.

What is the word مخابره in the verb مخابره کرد?

Is there a hidden connecting vowel (ezafe) between سیگنال and آنجا?

Yes! To say "the signal there," Farsi connects the noun سیگنال to the location آنجا using the ezafe. It is pronounced سیگنالِ آنجا (signal-e anja), literally translating to "the signal of there."

Is سیگنال a direct translation of the English word "signal" in all contexts?
