Idioms are phrases that have a meaning that is very different from its parts. Idioms have a figurative sense that has a socio-cultural context added to it. Using idioms in speech and writing, helps you to make your audience comfortable and involved in the process of communication. You can use idioms in everyday use, fictional and academic writing, but while using idioms, make sure to take into account whether figurative meaning of the idiom matches the symphony of the sentence. Adages or proverbs are common sayings that are used to offer truth or a lesson. They are sayings that are used from time memorials and have gained universal significance.
While idioms and adages seem similar, idioms carry a figurative meaning that is different from its literal use and adages are statements of common sayings that have become part of the everyday vocabulary for long.
It’s only by reading, learning and revising meanings of idioms and adages, you can master them and make your use of the English language enjoyable.
