Technology and Internet culture account for many of the latest revisions to the thorough and influential language guide, with words & phrases like ‘live-blogging’ and ‘mouseover’ also making the cut.

Elsewhere a diverse range of vocabulary has been officially recognised by the OED, ranging from ‘mochaccino’ to ‘headmistressy’ to ‘head space’. ‘Heart-in-mouth’ and ‘young adult’ are also included, defined as both nouns and adjectives.

There are some more unusual inclusions, such as ‘jolly hockey sticks’ (referring to an enthusiastic 'high society' lady others find irritating) and imbongi ('[in traditional African society] a composer and orator of poems praising a chief or other figurehead'). You can read the full list – loaded with slang, compound words and the occasional obscenity - here.

Meanwhile, the definitions of some previously recognised words have been expanded to include their more contemporary uses.

‘Tweet’, previously explained as the sound a bird makes, has been expanded to “to make a posting on the social networking service Twitter. Also: to use Twitter regularly or habitually.”
