Idiom vs Metaphor: Origin

The idioms and metaphors both come from the Greek world, here are their meanings as per their Greek origins. 

Idiom vs Metaphor: Meaning and Example

While idioms are fixed expressions with specific meanings, metaphors create vivid images by comparing different things. However, they both add colour and depth to the English language.

Idiom

An idiom is a phrase or expression that has a figurative meaning that is different from its literal meaning. Interestingly, idioms are culturally specific and usually cannot be understood by analysing each particular word in the idiom.

Example: “Love is a rose with thorns” means that love is an enriching experience, yet it is not without its trials and tribulations. It does not actually mean that love, which is intangible, has thorns.

Metaphor

A metaphor is a figure of speech that makes a direct comparison between two unlike things by stating that one thing is another. This comparison is used to communicate a deeper insight or to highlight similarities between the two.

Example: “Time is a thief” means that time steals moments from our lives, even though time is not literally a thief.
