European Deputy Executive Chairman Margaret Westger said that Europe will miss the "sense of humor" of the British and their "language proficiency".
"I will miss them because they came with their British culture and with their linguistic competencies that we do not all have," said Westerger on the eve of the UK's actual exit from the European Union.
Danish Margaret Westger, who has been the Competition Commissioner since November 2014, added that it was difficult for her to work outside of her mother tongue when she came to Brussels.
"I discovered that you should pay close attention to what you say, because it does not necessarily reflect your intention," she added.
"We speak a language, I don't know what to call it," she joked to a British journalist who asked her during a press conference.
She narrated that she once asked the European-British Commissioner, Jonathan Hill, "if he feels overwhelmed by the way we use his language," and she answered, "Of course not! "I am proud that you are trying."
Hill, which Festger says is "very close to him", took over as Financial Services Commissioner and resigned on June 25, two days after the UK voted for "Brexit".
In the European Union there are 24 official languages, but "Brexit" threatens the position of the English language within the EU institutions.
