A fun crossword to test students' knowledge of London's very own East End Cockney rhyming slang. An every day slang invented in the mid nineteenth century and still used by many Londoners today, who constantly add new words and phrases i.e Barrack Obamas means pyjamas. The crossword solution is included on the second page. Rhyming slang is a form of phrase construction in the English language and especially prevalent in dialectal English from the East End of London; hence the alternative name, Cockney rhyming slang. The construction involves replacing a common word with a rhyming phrase of two or three words and then, in almost all cases, omitting the secondary rhyming word (which is thereafter implied), in a process called hemiteleia, making the origin and meaning of the phrase elusive to listeners not in the know.
