What does D mean before a surname?

If you have ever come across a surname which starts with the letter “D,” you may have wondered what it signifies. The letter “D” before a surname is an abbreviation that references the word “de” or “di” in Italian, French, Portuguese, and Spanish.

The prefix “de” is derived from French, which in translation means “of” or “from.” In French, the preposition “de” can be seen before family names, which implies a lineage or a connection to a place. Similarly, in Italian, the word “di” is used for the same purpose.

Now one may wonder, why is this used? What’s the story behind it? Let’s explore a bit further.

The Origin of “D” before surnames

The use of ‘D’ or ‘de’ before surnames has existed for centuries to signify the aristocracy of a person or their family, or to signify descent from a particular place or region. Historically, surnames were created to differentiate one person from another. However, the addition of ‘de’ or ‘di’ before a surname implied that the person belonged to a particular family, town or region that held some level of prestige.

It is common knowledge that the use of surnames became popular in the Middle Ages, where people were primarily recognized by their first name, occupation, or location. The use of de’ was used as a prefix to identify someone’s family, employment title, hometown and so on. As society progressed people shifted towards more permanent titles that identified their lineage.

The use of ‘de’ before a surname showcased nobility and heraldry and was therefore associated with people of the upper class. It was a way for people to show their noble roots and distinguish their family from others. Today, some people still use it in the same way, making it a sign of pride in their traditions and lineage.

The Different Meanings associated with ‘D’ in Surnames

As mentioned earlier, the use of ‘D’ or the Italian counterpart ‘Di’ has different meanings. Here are some examples of what it may mean in different cultures:


In Spanish culture, ‘D’ is used as an abbreviation for the word “de,” which means “of” or “from.” It is a way for people to signify their connection to a particular family or place. For instance, the surname ‘de la Vega’ means ‘of the meadow or plain.’

In some cases, ‘D’ is added before first names of people who are of noble Spanish origin or come from a royal family. For instance, Juan Carlos I, the former King of Spain, is mostly known as King Juan Carlos, but his full Spanish name is “Juan Carlos de Borbón y Borbón-Dos Sicilias.”


In Portuguese culture, the use of ‘D’ is also an abbreviation for the word “de.” It is used to signify a family’s connection to a particular place. For example, the surname ‘de Braga’ means ‘of Braga,’ which is a city in Portugal.

However, it can also be used to identify people who belong to the nobility. Additionally, it can indicate a person’s lineage from a particular ancestor.


In the Italian culture, ‘D’ is an abbreviation for the word “di.” This prefix is used to signify someone’s connection to a particular place or a family. For instance, the surname ‘di Napoli’ means ‘from Naples.’

Moreover, the use of ‘di’ in Italian surnames was often a way for the nobility to signify their lineage and noble status. For example, Lorenzo de’ Medici means ‘Lorenzo of the Medici family.’ The Medici family was a prominent family of Italian nobles.


In French culture, the use of “de” was a way to convey nobility and to signify a person’s connection to a particular place or family. For example, the surname ‘de Valois’ means ‘from Valois,’ which is a region in France.

Moreover, in some cases, ‘de’ was added to a person’s first name to signify their noble lineage. For instance, Charles de Gaulle was a famous French statesman and military leader who was born in a noble family.


In conclusion, the letter “D” before a surname mostly signifies the prefix “de” or “di” in French, Italian, Portuguese, or Spanish. The prefix is a way to identify a person’s noble lineage, family connections, place of origin or residency. Nonetheless, the use of ‘D’ is most prominent in some cultures, mostly in Europe and Latin America, and is still widely used today. However, as society progresses, the significance of ‘D’ and the use of surnames are progressively evolving with people identifying themselves based on their professions, hobbies, or even ideologies.


What does D with apostrophe mean?

The letter D followed by an apostrophe (D’) is a contraction, which means it is a shortened form of two words. The contraction “D'” is a combination of the letter D with an apostrophe, which can mean two different things, depending on the context in which it is used.

The first meaning of D’ is that it is a contraction of “I would.” For example, the sentence “I’d love to go on vacation” means “I would love to go on vacation.” In this context, apostrophe D’ is used to signify a statement of intent or a desire. Similarly, “If I had more time, I’d finish reading this book” means “If I had more time, I would finish reading this book.” In this usage, the contraction of “would” to D’ is a way of expressing a hypothetical situation.

The second meaning of D’ is that it is a contraction of “I had.” For example, the sentence “I’d gone to bed early last night” means “I had gone to bed early last night.” In this context, D’ is used to signify a past event. Similarly, “If I’d known about the traffic, I would have taken a different route” conveys “If I had known about the traffic, I would have taken a different route.” In this case, D’ indicates a missed opportunity or regret about something that happened in the past.

D’ is a shorthand contraction that can mean “I would” or “I had.” Its meaning depends on the context in which it is used, and it is a useful tool to convey intentions, desires, and past events in a shorter form.

Why do French names have D?

If you come across French last names, you may notice a recurring theme of the letter “D” appearing in the middle the names. This is because of the existence of “particles,” which are terms used to describe the prefixes or suffixes used in surnames to indicate some underlying meaning.

In French, there are two particles – “de” and “du” – which often feature in surnames, and also have a specific purpose. “De” means “of,” while “du” is a contraction for “de” and “le,” meaning “of the.” These particles may seem confusing to those who are unfamiliar with them, but they actually provide valuable insight into the history and origins of the family names.

These particles generally indicate some land or feudal origin of the name, being associated with claims to a place. For example, the surname “De La Rosa” translates to “of the rose,” which might suggest ownership of a property or land that was once given the name “the rose.” Similarly, “Du Pont” – meaning “of the bridge” – might have arisen from ownership or building of a nearby bridge.

Particles were particularly popular during the medieval period, when feuds over land ownership were more prevalent, and having a particle in one’s name could reinforce their territorial claims. Some individuals also added particles to their names as a way of differentiating themselves from others who might share the same name.

However, not all French surnames have a “D” particle. The use of particles was more prevalent among the aristocracy, so it was certainly not a universal practice among the French population. Furthermore, some French last names might include other particles, such as “La,” “Le,” and “O,” for example.

The reason why some French last names have a “D” or particle is to indicate a property or territorial association. While this practice is no longer in widespread use today, it serves as an important reminder of the impact of history and geography on our modern-day identities.

What is the oldest family name in France?

The concept of family names or surnames as we know them today originated in Europe during the Middle Ages. Before that time, people were typically known only by their given name, or occasionally by a descriptive suffix like “the blacksmith” or “the baker.” However, as populations grew and people began to migrate more, it became more difficult to keep track of individuals without a consistent family name. Thus, the use of hereditary surnames became more widespread.

In France, many noble families trace their lineage back centuries or even millennia. However, it is difficult to definitively determine which family has the oldest family name, as records from the ancient past are often incomplete or unreliable.

That being said, one of the oldest and most distinguished noble families in France is the House of Montmorency. The origins of the Montmorency family can be traced back to the 10th century, when a man named Bouchard, a vassal of the King of France, was appointed as the first lord of Montmorency.

Over the centuries, the Montmorency family became one of the most influential in France. The family produced numerous knights, soldiers, and statesmen, and played a key role in many of France’s most important historical events. For example, a member of the family, known as Constable Anne de Montmorency, served as a military commander during the reigns of Francis I and Henry II.

Today, the Montmorency family is still active in French society, although their power and influence has waned somewhat over the centuries. Despite this, their legacy endures, and they remain one of the most respected and ancient noble houses in France.

Why do surnames start with de?

The use of the particle “de” as a prefix to surnames has its origins in Europe, particularly in Italy and Spain. In these countries, “de” is used to denote a person’s place of origin or affiliation with a particular family or clan. This is why “de” is often associated with noble families in these regions.

In Italy, noble families often used “de” to link their surname to a particular region or city. For instance, the famous Florentine family of the Renaissance, the Medici, sometimes used “de’ Medici” as part of their name, which means “of the Medici family”. The prefix was also often used by artists and writers to signify their association with a particular region or school of thought. For example, Leonardo da Vinci, the famous Italian artist and inventor, used “da” to indicate that he was from Vinci, a town in Tuscany.

In Spain, “de” is commonly used to indicate a person’s place of origin or family affiliation. In many cases, the prefix is only used in formal settings or on legal documents. For example, when a person with the last name “Garcia” moves from one region to another, they may use “de” and the name of their former town or city as a way of distinguishing themselves from others with the same surname. This is especially common in rural areas where people are often identified by their surname and place of origin.

It’s worth noting that the use of “de” is not exclusive to Italy and Spain, and similar prefixes are used in other countries and regions as well. For instance, in Scotland and Ireland, “Mac” and “O'” are often used to denote a person’s family affiliation or place of origin. In France, “de” is sometimes used to indicate nobility or association with a specific region or family.

The use of “de” as a prefix to surnames is a cultural tradition that has its origins in Europe. It is used to denote a person’s place of origin or family affiliation, and it is often associated with noble families or artists and writers who want to signify their association with a particular region or school of thought. While the use of “de” is most commonly found in Italy and Spain, similar prefixes are used in other countries and regions as well.

What is the prefix D in French?

In French grammar, the prefix ‘D’ (de, de la, d’, du, des) is a particle that serves various functions in the French language. It is a common but important aspect of French grammar that some learners may struggle to grasp at first. The prefix ‘D’ typically appears before a French surname, and while many people assume that it indicates nobility, this is not always true.

The use of the particle ‘D’ in French surnames can be traced back to the Middle Ages. During that time, French surnames were formed by adding descriptors that indicated a person’s occupation, origin, or physical attributes. For example, a farmer might be referred to as ‘Jean Le Fermier,’ while someone from the town of Nantes might be called ‘Sophie de Nantes.’ Over time, these descriptors were dropped, and surnames were formed using only the individual’s family name. However, the prefix ‘D’ remained in use for some families, regardless of their social status or occupation.

In modern French usage, the prefix ‘D’ appears before surnames and can indicate various things, such as nobility, a particular region of origin, or nothing at all. The use of the particle ‘D’ to indicate nobility is something of a misconception. While many noble families do have ‘D’ prefixes in their surnames, this is not always the case. Some commoners have ‘D’ prefixes in their surnames as well, and conversely, some noble families do not.

In addition to appearing before surnames, the particle ‘D’ also has several other functions in French grammar. For example, it is commonly used as a contracted form of prepositions such as de, du, and des. For instance, instead of saying ‘une bouteille de vin,’ a French speaker might say ‘une bouteille d’vin.’ This contracting of the preposition and the noun that follows it is a common way to shorten sentences in French and is used frequently by native speakers.

The prefix ‘D’ in French serves several purposes, from indicating nobility to shortening sentences through contracted forms of prepositions. Despite its long association with nobility, the use of the particle ‘D’ in surnames is not a reliable indicator of social status or occupation. Understanding the various ways in which ‘D’ is used in French grammar is an important aspect of learning to communicate effectively in the language.
