Princess Charlotte's full name includes sweet nods to two beloved late royals - including the Queen

Princess Charlotte's full name pays tribute to her grandfather, King Charles, her late great-grandmother, Queen Elizabeth II, and her late grandmother, Princess Diana

Prince William's daughter, Princess Charlotte, is third in line to the throne after her father and her older brother.

The nine-year-old, who was born on May 2, 2015 at St. Mary's Hospital in London, attends Lambrook School in Berkshire with her siblings, Prince George and Prince Louis. While she is commonly known as Charlotte, her full name includes two more names that pay tribute to two beloved late members of the Royal Family.

The child's full name is Charlotte Elizabeth Diana. Her first name, Charlotte, is the female version of Charles, alluding to her grandfather, the King. It could also be a nod to her mum's family, as Catherine's sister Pippa's middle name is also Charlotte.

Her second name, Elizabeth, is a tribute to her late great-grandmother, Queen Elizabeth II, while Diana is a sweet nod to William's mum, and Charlotte's grandmother, Princess Diana. When Charlotte was born, a statement was released, with the blessing of the late Queen Elizabeth, which read: "The [then] Duke and Duchess of Cambridge are delighted to announce that they have named their daughter Charlotte Elizabeth Diana. The baby will be known as Her Royal Highness Princess Charlotte of Cambridge."

At the time of her birth, Simone Simmons, a close friend of Princess Diana's, told Vanity Fair: "Diana would be over the moon. It's William's way of honouring his mother's memory. A way of making sure Diana's legacy lives on. This way she will never be forgotten. When Diana was alive, William promised her when he was King [that] Diana would have her HRH restored. This is his way of doing it."

At home, Charlotte's mum Catherine likes to call her Lottie. During a visit to Windsor Park stadium in Northern Ireland in 2019, influencer Laura-Ann Barr, who posts under @all.thats.pretty, revealed that the Princess of Wales referred to her daughter as Lottie rather than Charlotte during their conversation. It is thought that Charlotte's school friends also call her Lottie Wales, as a nod to the titles given to her parents by King Charles when her great-grandmother the Queen passed away.

According to Vanity Fair's royal correspondent Katie Nichol, William and Catherine have referred to Charlotte as the "Warrior Princess" due to her "feisty" personality. In addition, it's said that William uses the name "mignonette" when referring to his daughter, a French term of endearment.

Should she eventually become Queen, Charlotte can pick from any of her names to use in her official title. University College London's Constitutional Unit explained in 2022, ahead of King Charles III's Coronation, that the new monarch is "free to choose his own regnal title".

The unit adds: "King Edward VII chose Edward as his regnal title, although hitherto he had been known by his first name of Albert. King Edward VIII also chose Edward as his regnal title, although he was known to his family and friends as David." Following by this rule, Princess Charlotte could become the UK's first Queen Diana, or even follow in the footsteps of her late great-grandmother and become Queen Elizabeth III.
