To translate "I will travel tomorrow" into Arabic, we need to express a future action performed by the first-person singular. In Arabic, the future tense is formed by adding the particle سـ (for the near future) or سوف (for a more distant or general future) before the present-tense (المضارع) verb. The present tense of "travel" for the first person is أسافر, so the future form is سأسافر. Adding غدًا (tomorrow) gives the complete translation: سأسافر غدًا.
The option سافرتُ غدًا is incorrect because سافرتُ is in the past tense (الماضي), meaning "I travelled," which contradicts the future time marker غدًا. The option لن أسافر غدًّا uses the negation particle لن, which means "I will not travel" - the opposite of the intended meaning. The option أنا مسافرٌ اليوم means "I am a traveller today," which changes both the tense and the time reference.
Exam tip: When translating future-tense sentences into Arabic, always use سـ or سوف + the المضارع form. Check that the time adverb (غدًا, اليوم, etc.) matches the tense of the verb.
