An idiom (also called idiomatic expression) is an expression, word, or phrase that has a figurative meaning conventionally understood by native speakers. This meaning is different from the literal meaning of the idiom’s individual elements. In other words, idioms don’t mean exactly what the words say. They have, however, hidden meaning. 

For your IELTS Speaking test, idiomatic language can be important because it is one of the elements in this component of the test the examiner looks for.

Origin 

Although generally an official book in which misdemeanours and their perpetrators were noted down, the phrase perhaps originated in the black-bound book in which evidence of monastic scandal and abuses was recorded by the commissioners of Henry VIII in the 1530s before the suppression of the English monasteries. 

In a sentence

In a sentence

As blind as a bat

Meaning 

Having very bad eyesight. Informal 

Origin 

Probably arising from the bat’s nocturnal habits and its disorientated flutterings if it’s disturbed by day; A mid-17th-century collection of idioms has this expression in the form “blind as a bat at noon”. The poor eyesight of bats (and less frequently, moles) has been proverbial since the late 16th century.
