Difference Between Phrase and Idiom

Words alone do not contribute or have no definite meaning, therefore words are paired up together to make sentences and further used in such manners to make them more bewitching. Best examples of such tools can be phrases and idioms. Both of them are sometimes misunderstood and considered the same, which is not right at all.

Phrase vs Idiom

The main difference between Phrase and Idiom is that Idiom is a type of phrase with figurative meaning and it is understandable only if the person is familiar with it, whereas the phrase is understandable by everyone as it has a literal meaning. Another difference could be that the idioms are fixed whereas so such fixation is with the phrases.

Phrase vs Idiom

Phrases are small collections or groups of words with some literal meaning. They are very easy to understand and each word of it contributes to its meaning. They can be changed easily without any errors. They cannot be understood by looking at individual words.

Idioms are words/word that is not easily understandable, and cannot be changed. It can be a group of words or even one word. Translating idioms words by words in the literal meaning are not possible will give wrong results. Therefore it is important to understand the idiom as a whole.
