The Oxford Word of the Year 2018 is… “toxic”.
From the article published by Oxford Dictionaries:
“Data show that, along with a 45% rise in the number of times it has been looked up on oxforddictionaries.com, over the last year the word toxic has been used in an array of contexts, both in its literal and more metaphorical senses.”
“One of the many environmental issues discussed this year has been the toxic algae disaster in Florida, US. Thanks to a central role in the state’s Senate mid-terms race, toxic algae garnered so much commentary that ‘algae’ featured as the ninth-most frequently seen toxic collocate for 2018.“
