Oxford Dictionaries declares 'climate emergency' the word of 2019
from the article:
"And for those protesting that “climate emergency” is two words, as the Australian Broadcasting Corporation’s resident linguist explained in 2017, single words can consist of two parts. Such multipart constructions, like “heart attack”, “man-of-war” or the 2017 American Dialect Society word of the year “fake news”, are commonly accepted by linguists as words."
