What did Princess Diana call Prince Philip?

How Diana Addressed Prince Philip Reveals a Tender Side of the Royal Family

Amid the complexities of royal life and the turbulence of her marriage, Princess Diana still managed to maintain respectful and affectionate ties with members of the royal family — including Prince Philip. According to letters from 1992 uncovered by The Associated Press, Diana referred to the Duke of Edinburgh as "Dearest Pa", a revealing glimpse into their personal relationship.

This intimate address might surprise those who remember the often-stiff public image of the royal family. "Dearest Pa" suggests not only respect but a sense of closeness, almost like a daughter speaking to a father figure. At the time, Diana’s marriage to Prince Charles was under intense strain, and Philip’s response to her overtures was reportedly supportive. He even offered to help the couple navigate their growing problems — a gesture that underscores a lesser-known, more compassionate side of the usually reserved duke.

Rarely did Diana’s private correspondence offer such candid emotional insight. This small but significant detail — the use of “Pa” — speaks volumes. It hints at a dynamic that wasn’t defined purely by protocol or hierarchy, but by personal bonds that persisted behind palace walls. While their relationship evolved over time, especially as tensions within the royal structure intensified, these letters show that there was, at least for a moment, an attempt at familial solidarity.

In hindsight, Diana’s warmth toward Philip contrasts with the more formal, sometimes strained relationships she had with other senior royals. Her choice of words — simple, affectionate, human — reminds us that beneath the grandeur, the royal family, like any other, grapples with love, conflict, and the search for connection.
