Nomophobia, defined as "fear or worry at the idea of being without your mobile phone or unable to use it", was chosen as the word of the year for 2018 by Cambridge Dictionary, Xinhua reports according to Dailymail Sunday.
The other three words were chosen in a finalist were "gender gap", "ecocide" and "no-platforming".
According to a statement issued by Cambridge Dictionary, the earliest use of the word nomophobia was 2008, which was emerged in a report commissioned by the UK Post Office.
Cambridge Dictionary said "Your choice, nomophobia, tells us that people around the world probably experience this type of anxiety enough that you recognised it needed a name."
"It then began to appear in UK media and has since spread around the world. Having proved its staying power, it was added to the online Cambridge Dictionary earlier this year," it said.
In addition, some other well-known dictionaries have also announced their words of the year for 2018.
At the Collins Dictionary, the word of the year was "single-use", referring to products such as plastic bottles, straws and bags that are used only once before disposal.
For Oxford Dictionary, it was 'toxic', which was increasingly used to describe views, relationships, cultures and even politicians.
