|Towards more picturesque speech™
There is no gerundive in English; the closest you get is a passive infinitive like “books to be read”, combining a transitive verb and its object with a sense of obligation. But wouldn’t you just use the active infinitive and avoid that ugly passive: "books to read".
- quod erat demonstrandum — because that is the very thing one seeks to prove;
- mutatis mutandis — changed in ways that must be changed.
See also gerund, which is capable of social snobbery.
