/ˈmɑː.dʒɪ.neɪt/
verb · transitive · etym: noemic-latinate · margo (edge, border) + -ate
to write in the margins of a book one will not finish.
to marginate is honest. it admits that the reader and the book have parted ways, but politely — with notes, with questions, with arrows toward passages that will not now be reached. the marginalia wing is composed entirely of such gestures.
a margined book is not abandoned. it is colonised. the reader leaves a small weather report on each page they did manage, and a kind of farewell on the page where they stopped. compare the footnotelore of others who marginated the same book before you, and the palimpsest beneath.
in a sentence: "i have been marginating this novel since spring. by page sixty i had said everything i needed to."
