A hilarious tour of the state of our mother tongue, from the people who brought you Am I Alone In Thinking . . . ?, Sign Language is a collection the most inappropriate, confusing, poorly translated and mind-bogglingly bizarre signs from around the world.

Few things amuse and appal Telegraph readers as much as the abuse, misuse, mistranslation and outright mangling of the English language. So, for the past three years the Telegraph has run a weekly feature inviting members of the public to send in photographs of menus, health and safety warnings, road signs, adverts, headlines and personals columns – anything in which the language has gone egregiously, hilariously and, usually, unintentionally wrong.

Entitled Sign Language, the published selection of the very best images has become one of the newspaper's most popular features, attracting over 300,000 online visitors every week and attracting thousands of submissions from around the world.

Now, we present the very best of Sign Language – both seen and unseen – and offer a timely warning about the imperilled state of modern English.
