What do you call of people who write in measure language?

There isn't a single, universally accepted term for people who write in measure language. However, depending on the context, you could use several terms:

Formal:

* Writers in measure language: This is the most straightforward and accurate term.

* Measure language poets/authors: This emphasizes the specific genre or field.

Informal:

* Measure language users: This is a broader term that encompasses anyone who uses measure language, including speakers and writers.

* Metric poets/authors: This term focuses on the use of meter, which is a key element of measure language.

Specialized:

* Classical poets/authors: This term may be used for writers who use specific measure languages like dactylic hexameter (used in classical Latin and Greek poetry).

* Rhythmic poets/authors: This term emphasizes the rhythmic quality of measure language.

Ultimately, the best term depends on the specific context and what you want to emphasize. It's also worth noting that some languages, like Japanese, have their own specific terms for different types of measure language poetry.

Can you provide me with more context about what you are looking for? For example, are you interested in a term to describe people who write in a specific measure language, like iambic pentameter? Or are you looking for a more general term?
