ご指名質問（回答）:beaming

Sugar君からの指名質問に答えたいと思います。文中でのbeamingでは「喜びにあふれた、晴れやかな」（『ジーニアス英和辞典　第３版』大修館）という語義になり、Oxford Dictionaries Onlineにも目を通してみますと’ smiling broadly; grinning’と載っていました。(Shou-VR*)

UK royal baby: New photos of Prince George released by Kensington Palace
(CNN) -- What a sweet snapshot: Mom, dad, the baby boy ... and two charming canines.
It's one of two photos released Tuesday by Kensington Palace of the Duke and Duchess of Cambridge, their newborn son, Prince George, and a couple of four-legged friends.
The photos were shot by Michael Middleton, Catherine's father, in early August in the garden of the Middleton family home in Bucklebury, Berkshire.
One portrait shows Catherine, the Duchess of Cambridge, beaming while holding the swaddled George, who is third in line to the British throne. The happy husband, Prince William, is beside them, all smiles.
