But Twitter has managed, much like Google, to wheedle its way into our everyday vocabulary and has now become the most popular word in the English language.

The site, which allows its 20 million users to transmit 140 character messages instantly to whoever is interested, has come top in a survey of the most-used phrases of the year.

The survey was carried out by Texas-based company Global Language Monitor, which studied the internet and media over the course of the last 12 months, recording which words were most frequently used.

And Twitter, apparently, is the word on everyone's lips. Barack Obama could only manage second place while H1N1, the scientific term for swine flu, understandably sneaked into third spot.

Finances were high on the list too, with "deficit", "bonus" and "unemployed" all placed within the top 15.

GLM's Paul Payack told the Daily Mail: "In a year dominated by world-shaking political events, a pandemic and the aftermath of a financial tsunami, the word Twitter stands above all the others."

How much 'tweeting' revolved around the "world-shaking political events" and the "financial tsunami" is as yet unclear.
