Sometimes I see sentences with "state of the art" and others with "state-of-the-art".

What is the difference if it has a hyphen?


The difference is that without hyphens, it's a noun, and with hyphens, it's an adjective. So you might say that a given piece of technology "represents the state of the art in its field," or you could refer to it as "state-of-the-art technology."

"state of the art" is a noun: it refers to the actual state of progress in a given field.

The most recent stage in the development of a product, incorporating the newest technology, ideas, and features

the state of the art in 3D printing

"state-of-the-art" is a compound adjective: it refers to something (often a product or piece of technology) that uses the latest technology in a given field.

Belonging or relating to the most recent stage of technological development; having or using the latest techniques or equipment.

our scientists work in state-of-the-art facilities

  • They probably downvoted your answer because it provides no dictionary for your claim of the use of the phrase as a noun and as an adjective. Have you made up these examples yourself or have you found them somewhere? They are a bit awkward and do not help to explain your point very much. Try simpler sentences.
