Communication between two people is not just the exchange of words. It is the clash of two mental systems, two ways of processing reality, two ways of interpreting what is said and what is left unsaid. This is where astrology offers us a key that, if applied well, can change the way we relate to others: each person listens and expresses themselves through their own Mercury.

It’s Not Personal, It’s Their Mercury

How many times have we felt frustrated because someone doesn’t understand us? Or worse, because we feel like they’re not even listening in the way we want to be heard. But when we understand that the other person has their own way of processing information, we can see that most of the time, it’s not about a lack of interest or bad intentions, but a difference in mental language.

Each Mercury has its own perception filter:

Mercury in Aries

• Thinks fast, speaks directly, and gets to the point. Doesn’t like wasting time on details.
• Can be impulsive in responses and say what they think without a filter.
• Doesn’t care too much about long explanations—just wants action.

Mercury in Taurus

• Needs to process information calmly before responding.
• Prefers clear, practical, and unhurried communication.
• Doesn’t change opinions easily and struggles with fast-paced discussions.

Mercury in Gemini

• Talks fast, constantly changes topics, and is extremely curious.
• Doesn’t like diving too deep into a single subject—prefers exploring many ideas.
• May seem scattered, but has a flexible and adaptable mind.

Mercury in Cancer

• Processes information through emotion and memory.
• Cares more about tone and intent than the exact words.
• Can be subjective in communication and remember past details intensely.

Mercury in Leo

• Speaks with confidence and conviction, needs to be heard.
• Expresses themselves dramatically and creatively, full of color and enthusiasm.
• Can seem dominant in a conversation but genuinely just wants to inspire.

Mercury in Virgo

• Analyzes everything in detail, needs precision and order in information.
• Prefers to speak when there’s something useful to say.
• Can be critical or perfectionistic in expression.

Mercury in Libra

• Seeks balance in communication and prefers to avoid conflict.
• Likes to analyze both sides of a situation before giving an opinion.
• May seem indecisive because they struggle to take a firm stance in conversations.

Mercury in Scorpio

• Speaks little but deeply. Doesn’t say something until they are sure.
• Reads between the lines and detects what is left unsaid.
• May seem intense or distrustful, but their communication is direct and transformative.

Mercury in Sagittarius

• Loves exploring ideas and philosophies, communication is enthusiastic.
• Can be brutally honest and say what they think without a filter.
• Gets bored with details—prefers the big picture and inspiration.

Mercury in Capricorn

• Speaks in a structured, concrete way with a clear objective.
• Doesn’t waste time on abstract theories—seeks practical results.
• May seem cold, but just wants to ensure their words have weight.

Mercury in Aquarius

• Thinks in an original and disruptive way, likes challenging conventional ideas.
• Speaks in abstract and theoretical terms, looking for patterns and connections.
• May seem emotionally distant, but is more focused on the concept than the person.

Mercury in Pisces

• Communicates symbolically, intuitively, and sometimes diffusely.
• Picks up more on emotions than on concrete words.
• Can be poetic in expression but also forget easy details.

The Art of Speaking to Someone Else’s Mercury

When we understand these differences, we can make a fundamental shift: instead of insisting that others understand us in our language, we learn to speak in theirs.

If you want Mercury in Capricorn to listen, give them clear and concrete information. If you’re talking to Mercury in Sagittarius, keep their interest by making the conversation more exploratory. If you’re dealing with Mercury in Scorpio, give them content with emotional and symbolic depth.

It’s not about changing who we are, but about learning to better sync our frequencies with those around us.

The Power of Not Taking Things Personally

When you realize that someone isn’t responding as you expected, pause and ask yourself: is this a rejection, or just a difference in how we perceive information?

Most of the time, the other person is not ignoring or dismissing you. They are simply processing through their own mental structure.

And in that moment of understanding, something shifts. You stop fighting frustration and start seeing communication for what it really is: an act of translation between minds that perceive the world differently.

Astrology, when used correctly, doesn’t put us in boxes. It opens up the possibility of better understanding others—and with that, finding smarter ways to connect.

And maybe, just maybe, the world would be a little easier if we stopped taking everything so personally.
