Britain's heir to the throne, William, and his wife, Catherine, on Tuesday made their first visit to Wales since becoming the new Prince and Princess of Wales.
William automatically inherited the title on the death of his grandmother, Queen Elizabeth II, when his father - the previous Prince of Wales - became king.
The visit came as media reports said William had no plans for "any kind" of investiture.
King Charles III spent time learning Welsh at university before he was crowned by his mother in a televised ceremony at Caernarfon Castle in July 1969 when he was 20.
During the elaborate investiture ceremony, the queen placed a coronet on Charles's head and helped arrange robes around his shoulders.
He pledged allegiance to his mother with the words: "I, Charles, Prince of Wales, do become your liege man of life and limb."
The domestic Press Association news agency reported that rather than planning an investiture, William was focused on deepening the trust and respect of the people of Wales over time. But Tuesday's visit, as the mourning period following the death of the queen ended, proved to win the hearts of the Welsh over.
Rev. Steven Bunting, who hosted the couple at St. Thomas's Church in Swansea, home to a food bank and baby supply hub for families in need, told People William revealed he'd been learning Welsh.
"He talked about learning Welsh and shared some Welsh phrases he's trying to do," Bunting said, adding he'd been practicing phrases "paned" (a cup, such as of tea) and "bara brith" (traditional Welsh tea bread).
He added: "He is throwing himself into the new role. The fact that they've come straight here on day one says it all."
Meanwhile, Rachel Bunting, the wife of the reverend who runs Baby Basics at the church, said: "We don't get royal visits here often and today made a massive difference. You can see kids everywhere and they're so excited.
She added: "They're probably the most approachable royals."
Kate, while conscious of the history associated with the role, wishes to create "her own path", a royal source was quoted as saying in the days after the queen's death on 8 September.
