HASHTAG has been chosen by Oxford University Press as its Children’s Word of the Year for 2015.

The publishing company analysed more than 120,000 short stories submitted by children to a BBC competition.

It said the word ‘hashtag’, or #, had started to be used to add dramatic effect, rather than just as a search term on social network Twitter.

Other words in the top 20 included selfie, blog, YouTube and youtuber.

But the stories also contained many mentions of words associated with the First World War, such as Tommies, shrapnel and mustard gas.
