Verbiculture: the production of words. 

Yep.  It’s really a word.

From Latin verbum (word) and the Latin verb colo, colere, colui, cultus: to live in, inhabit; till, cultivate, promote growth.

Verbiculture, which shows up in almost no dictionaries, was coined in 1873 by Coined by Fitzedward Hall, in “Modern English.  Mr. Hall was one of the early collaborators in the Oxford English Dictionary (OED). 

Ironically, verbiculture, meaning, the production of words, has not caught on.

Men ever had, and ever will have leave,

To coin new words well suited to the age,

Words are like leaves, some wither every year,

And every year a younger race succeeds.

-Horace, Roman poet (65 BC)
