Question: How do you translate the adjective ‘pacifist’ into Latin?

‘pacifistus, a, um’ seems incorrect to me since all the words I’ve found with the suffix *-ista* are nouns, not adjectives.

Answer: 
*Pacifista* and *pacifismus* (both employed by [Vicipaedia](https://la.wikipedia.org/wiki/Pacifismus), by the way) are not exactly the sort of coinage that pleases *Latini* of the old school in the first place. Too literal, unclassical, would stick out like a sore thumb in a letter of Cicero's.

Now if a revolutionary is *novis rebus studens* ([1 Cat 3](https://www.thelatinlibrary.com/cicero/cat1.shtml#3)), does it not stand to reason that a pacifist is ***paci studens***? This has the advantage that it can be used adjectively as well as substantively.

The downside is that this sort of expression sounds pretty general and does not convey it is referring to a fixed idea. Pacifism is an ideology and a movement (however amorphous) that has a name; being zealous for peace is a character trait. (1) Nevertheless, the adjective *pacifist* is also often used generically to describe a personal disposition without wanting to make reference to the pacifist movement, and if that is the meaning you are aiming for, you may find *paci studens* to your liking (or, indeed, you may use other forms of *studere*).

(1) A particularly egregious example for this issue was the translation for "fascism" I read in a certain book, which was *exaggeratum suae gentis studium*.
The suffix *-isticus* seems quite productive in neo-Latin, and even in classical Latin we have *sophisticus* and *syllogisticus*. If you aren't looking for something fancier, I'd go with that.
