Idioms and phrases are figurative expressions with non-literal meanings. These are used fondly to add flair and vibrancy to the language. Idioms usually have meanings different from the literal meaning of the words in them.

Idioms are categorised into four main types: pure idioms, binomial idioms, partial idioms, and prepositional idioms. Phrases whose non-literal meaning is completely different from the literal words in them are called pure idioms. Whereas when two words or phrases are linked by a conjunction, they are called binomial idioms. 

And phrases that contain one literal part and one non-literal part are called partial idioms. Whereas idioms that contain a prepositional phrase or verb combined with an adverb or preposition are called prepositional idioms.
