scripturient

In a sentence

Where it comes from

From Latin 'scripturiens,' the present participle of 'scripturire,' a desiderative verb formed from 'scriptura' (writing) and ultimately from 'scribere' (to write). It was used in learned Latin to express a strong desire to write, and appears in English in the 17th–18th centuries, though it has always been rare and somewhat pedantic.
