Ahora vivo en Bogotá.

In Spanish, the simple present can describe both habitual states and ongoing situations. Unlike English, you don’t need a separate continuous tense for “to be living.”

• Vivo en Bogotá = I live in / I am living in Bogotá
• A continuous form exists (estar
  • gerund), but it’s less common for stating where you live.

Yes, but it implies a temporary or very current situation. Use it if you want to stress that your living arrangement is recent or short-term:

• Estoy viviendo en Bogotá (I’m living in Bogotá right now, perhaps temporarily)
• Vivo en Bogotá (I live in Bogotá, as my usual residence)

Spanish verb endings carry person information, so subject pronouns are optional. We include yo only for emphasis or contrast:

• (Yo) vivo en Bogotá. (I live in Bogotá.)
• Yo vivo en Bogotá, pero mi hermano vive en Medellín. (I live in Bogotá, but my brother lives in Medellín.)

The verb vivir pairs with en when referring to residing in a place.

• Vivo en Madrid, en Buenos Aires, en un barrio…
  Other prepositions have different uses:
• viajar a (to travel to)
• venir de (to come from)
• mudar(se) a (to move to)

Yes. Ahora (now) is flexible in Spanish. You can say:

• Ahora vivo en Bogotá. (common)
• Vivo ahora en Bogotá. (focus on the time)
• Vivo en Bogotá ahora. (emphasizes the new situation)

Spanish accent rules require a written accent when stress falls outside the default pattern.

• Words ending in a vowel, “n” or “s” are normally stressed on the next-to-last syllable.
• Bogotá is stressed on the last syllable (bo-go-TÁ), so it needs an accent mark.

Pronounce each vowel clearly and stress the last syllable:

• Bo (like “bo” in “bore”)
• go (like “go” in “gone”)
• TÁ (like “tah,” but stronger)
