Radacanu has thrilled fans around the world on and off the court, as the multilingual teenager gives interviews in three languages.
The Bromley girl represents Great Britain in tennis but her heritage is diverse, she is currently taking part in the Transylvanian Open in Romania which is a place close to her heart.
So, what languages can she speak and where was she born? This is what you need to know.
How many languages can Emma Raducanu speak?
Emma Raducanu speaks three languages; English, Mandarin and Romanian.
In recent weeks she has demonstrated her fluent second languages, including speaking in Mandarin during a winner’s interview at the US Open.
She addressed the crowd of onlookers and those watching at home, saying in Mandarin: “Hi everyone, I wanna say thank you guys and I hope you could enjoy my tennis.
“I’m thrilled to win. Love you all, see you.”
Then during an interval at the Transylvania Open training sessions in Romania, she told the home crowd she was shy to speak Romanian as she isn’t hugely fluent, but hoped the longer she spent in the country the better it would get.
Where was she born and what is her heritage?
While Emma represents the UK in her tournaments, she was actually born in Canada and spent two years there before moving to England with her parents.
She has a Romanian father and a Chinese mother, her paternal grandmother lives in Bucharest and Emma would regularly fly to Romania to visit her as a child.
The 18-year-old told reporters at the Transylvania Open, which takes place from 23-31 October 2021, that she hopes to spend some time there after the competition comes to an end.
“I love Romania. I used to come once or twice a year to visit my grandmother, who lives in Bucharest, while growing up. It is an hour’s flight from here,” she said. “When the tournament is done, I’d love to pop over to Bucharest to be able to visit her. I haven’t seen her for two-and-a-half years.”
The teenager has also been welcomed with open arms by her father’s home country, as crowds celebrated her with a mexican wave during one of her practice matches.
Raducanu said of the crowd: “The welcome I got was really, really nice and I always love coming back.
“The people here are really friendly, great humour and good food. I have great memories from this country. It is really nice to be back.
“The thing is I can understand like 80 percent of Romanian. I don’t want to big myself up.
”I just really struggle to find my words and vocab. When I got told about this thing at the end of the session, and I would be speaking to the crowd, I was thinking of my vocab at the changeovers.
“The more I spend time here, the more I immerse myself in the language, and I can pick it up reasonably fast.”
