FLOTUS, facepalm, net neutrality along with terms from recent advances in science — such as CRISPR — are among over 1,000 new words added to the Merriam-Webster dictionary.

The new entries include borrowings from foreign languages as well as words from tech, medicine, pop culture, sports.

“The work of revision is ongoing and constant; even though it seems that the latest slang gets the most attention when dictionaries issue lists of new words, the additions come from the whole range of registers and from every corner of the language,” the dictionary said in its blog.

‘Seussian,’ relating to or suggestive of the works of Dr Seuss, is now in the online dictionary, along with ‘conlang’ — an invented language like Klingon — and ‘prosopagnosia’ (an inability to recognise faces). New tech terms such as abandonware and botnet have also been included in the list of new words.
