from write (vb.) + -ative; after talkative
EXAMPLE
“… I find, tho’ I have less experience than you, the truth of what you told me some time ago, that increase of years makes men more talkative but less writative: to that degree, that I now write no letters but of plain business, or plain how-d’ye’s, to those few I am forced to correspond with, either out of necessity, or love …”
