The Wordsworth Dictionary of Idioms — Martin H. Manser

You have asked a friend to keep a secret and he or she blurts out, 'Trust you to open your big mouth!'
You agree with someone in having the same idea or opinion and you say 'Great minds think alike'.
This dictionary explains such idiomatic phrases used in typical English conversations. Modern spoken English contains many expressions that the average English speaker scarcely thinks about and foreign learners find difficult. This dictionary explains such expressions.
Written by leading British lexicographer Martin H. Manser, it will be found useful by all speakers of English. Those with English as their native language will be reminded of the wide range of phrases used in everyday speech - think of all right, I mean and you know. Students learning English as a second or foreign language will find help here that is just not included in other reference books - so this dictionary will increase the understanding of what has been heard and will also develop a proficiency in using idioms.
