Most Spanish speakers say “por cierto” for “by the way,” and many also keep “BTW” in chats when the vibe is casual.
If you’ve typed “btw” a thousand times in English, you’ve already got the habit: you’re slipping in an extra thought, changing the subject a bit, or adding a side detail. In Spanish, you can do the same thing—just with a few options that fit different tones.
This article breaks down what “btw” means, the closest Spanish matches, when each one sounds natural, and how to drop it into a sentence without sounding like a translation app. You’ll also see what Spanish speakers write in texts when they’re moving fast.
What “Btw” Is Doing In A Message
“Btw” is short for “by the way.” It’s not just a translation problem; it’s a tone problem. In English, “btw” feels light, quick, and a little sideways—like you’re tossing in a thought that matters, but you don’t want to make it a big deal.
Spanish has that same move. The trick is picking the phrase that matches your setting. A close friend? A class chat? A teacher? A work email? Spanish has options that shift from casual to formal without sounding stiff.
Three Common Intentions Behind “Btw”
- Adding a side detail: you remembered something small and want to attach it.
- Changing topic slightly: you’re steering the chat to a new point.
- Throwing in a reminder: you’re tagging a practical note without making it heavy.
Best Natural Translations For “By The Way” In Spanish
If you want the closest everyday match, start with “por cierto”. It’s common, smooth, and works in both speech and writing. It’s the default choice when you want “by the way” without drama.
Next up: “a propósito”. This one leans closer to “speaking of that” or “on that note.” It often points back to something already mentioned, so it can feel a touch more intentional than “por cierto.”
Then there’s “por cierto, hablando de…” or “ya que mencionas…” when you’re linking the new point to something that just came up. Those feel conversational and clear.
When “Por Cierto” Sounds Right
Use “por cierto” when your extra point is a side comment. It fits quick reminders, small updates, and casual topic shifts. You can place it near the start of the sentence or after the first clause, depending on rhythm.
When “A Propósito” Fits Better
Use “a propósito” when your new thought connects to the last topic. It can also carry a slightly more deliberate feel, like you’re tying threads together. In speech, it often shows up with a brief pause before it.
When Spanish Speakers Keep “BTW”
In chats, gaming servers, group messages, and quick DMs, plenty of Spanish speakers just type “BTW” anyway. It’s short, widely understood online, and it signals the same casual “side note” energy as in English.
If you’re learning Spanish for real conversation, it’s still worth mastering “por cierto” first. It works everywhere, and it doesn’t rely on internet habits.
Btw Meaning In Spanish In Real Situations
Here’s the part that saves you from awkward phrasing: Spanish choices depend on who you’re talking to and how direct you want to sound. A phrase can be correct and still feel off if the tone doesn’t match.
Casual Chat With Friends
“Por cierto” is the safest bet. It feels normal in Spain and across Latin America. If you’re texting, you can also shorten your message and let punctuation do the work: a dash, a new line, or a short follow-up sentence.
Class, Study Groups, And School Messages
“Por cierto” still works, and so does “a propósito.” If you’re reminding someone about a deadline or material, Spanish often prefers a direct sentence after the connector. Clean and clear beats fancy.
Work Messages And Formal Writing
In formal writing, “por cierto” can still appear, but many writers switch to calmer connectors like “por otra parte” or “con respecto a…” depending on the goal. If you’re writing to a boss or client, skip “BTW” and choose a full Spanish phrase that matches the tone of the message.
One warning: avoid literal word-for-word transfers that sound like English wearing a Spanish costume. Spanish doesn’t need an extra connector every time you add a thought. Sometimes a clean new sentence is the most natural move.
Spanish Options Compared Side By Side
You can treat this table like a quick picker. Start with what you mean in English, then grab the Spanish phrase that carries the same vibe.

Examples That Sound Like A Real Person
Below are sample lines you can steal and reshape. Read them out loud once. If it sounds like something you’d say, you’re good.
“Por Cierto” Examples
Por cierto, ¿ya comiste? (By the way, did you eat yet?)
Te mando el archivo hoy. Por cierto, mañana no estaré. (I’ll send the file today. By the way, I won’t be around tomorrow.)
Por cierto, gracias por ayudarme ayer. (By the way, thanks for helping me yesterday.)
“A Propósito” Examples
A propósito, ¿cómo te fue en el examen? (Speaking of that, how did the exam go?)
Estábamos hablando de viajes. A propósito, ¿ya sacaste el pasaporte? (We were talking about trips. Speaking of that, did you get your passport?)
Topic Shift That Doesn’t Feel Random
Por cierto, cambiando de tema, ¿qué planes tienes el sábado? (By the way, changing the subject, what are your plans on Saturday?)
Replying To What Someone Just Said
Ya que mencionas eso, tengo una duda. (Since you bring that up, I have a question.)
Where To Place It In The Sentence
Placement changes the feel. Spanish gives you a few natural spots, and each one has a slightly different rhythm.
At The Start
This is the classic setup. It signals the shift early.
- Por cierto, + your side note
- A propósito, + your linked thought
After Your Main Point
This feels casual, like you remembered something mid-stream.
- Main sentence. Por cierto, side note.
- Main sentence; por cierto, side note.
As A Short Tag
“Por cierto” can act like a tag at the end. It’s common in chat-style writing.
- Nos vemos a las ocho, por cierto.
Texting Shortcuts You’ll See From Spanish Speakers
Spanish texting often skips extra words and leans on punctuation. People also shorten common phrases. Some shortcuts are shared across countries; some are local. If you’re learning, recognize them first, then decide if they match your style.
| What You See | What It Means | Where It Fits |
|---|---|---|
| BTW | By the way | Casual chats, online spaces |
| x cierto | por cierto | Texts with friends; not formal |
| pt | por cierto | Fast typing; not universal |
| aprop | a propósito | Rare; depends on the group |
| — | Topic shift without a phrase | Any casual message |
| “Oye,” | Soft opener before a new point | Friends, classmates |
| “Ah,” | Sudden add-on thought | Speech-like texting |
Common Mistakes That Make It Sound Translated
These slip-ups show up a lot with learners. Fixing them makes your Spanish feel more natural fast.
Using “Por El Camino” For “By The Way”
In English, “by the way” has nothing to do with a road. In Spanish, “por el camino” means “along the way” in a literal sense. It won’t carry the “side note” meaning you want.
Forcing A Connector Every Time
English loves little connectors. Spanish can be cleaner. If your add-on thought is short, a new sentence often feels better than any phrase.
Overusing “A Propósito”
“A propósito” is great when the new point connects to what you were already talking about. If you use it for random side notes, it can feel off. In those moments, “por cierto” fits better.
A Simple Way To Choose The Right Phrase
When you’re unsure, run this quick mental check:
- If it’s a random add-on, pick por cierto.
- If it connects to what was just said, pick a propósito or ya que mencionas eso.
- If it’s formal writing, skip “BTW” and use a calmer connector like con respecto a.
- If the chat is casual and everyone types in English shortcuts, “BTW” can be fine.

Quick Recap You Can Hold In Your Head
