Fitspiration and clictivism are among 300 words that have been added to an online dictionary produced by Oxford University Press. monitors current trends in the use of modern English to come up with new additions.

Fitspiration describes a person or thing that serves as motivation for someone to sustain or improve health and fitness while clictivism refers to actions performed on the internet in support of a political or social cause, regarded as requiring little time or involvement, such as signing an online petition.

Other words that have made the cut include HIIT - an acronym for high intensity interval training - and Bronde, referring to blonde hair with sections of brown.

The phrase drunk text, denoting a text message sent whilst inebriated which is often embarrassing or foolish, is another new entry.

Oxford Dictionaries' head of content development Angus Stevnson said the wide range of new terms complemented reports of recent socio-cultural trends, such as those suggesting millennials are choosing to spend less money on alcohol and more money eating exotic world foods.

He said: "You could say that a lot of the words we've added are a bit strange - particularly the blended words made up of two words joined together.

"If you take the word fitspiration, you could say 'that's a really ugly word' or 'that's not a proper word'.

"But if you go on Google or many people's Facebook pages, you'll find that there is a big usage or perhaps they're part of their interests and you can't really say that that person's interests aren't valid if there isn't another word for it."

Other additions include aquafaba and superfruit.
