Ah, transitive, yes. Not being a native English speaker, I don't have all the grammatical terms at the tip of my tongue.
And yes, it's about the Latin. But IIRC, the Latin-derived -nt suffix does carry the inherent meaning of "causing something else to X" - which means you can't blindly apply it to any verb. I really should refresh my Latin, though. It's been a long time since I used it.
It's been a few years since I had any Latin, so this may be wrong. If I recall correctly:
Start with a verb, say your usual amo, amas, amat
(I love, you love, he/she/it loves); the infinitive is amare
(to love) (I think). We then form the adjective amans
, (loving). Being a Latin adjective, amans
must decline; these verb-formations generally end up third-declension, amans, amantis
. I think. You can then go on to get a noun, something-that-loves -- I think amans, amantis
can work for that, too; Latin adjectives stand in for nouns relatively easily. On the other hand, amat-
is an adjective root meaning 'loved'. Of course amo, amare
isn't one of the verbs which made it into English -- except, of course, as 'something to be loved', amanda
So, accelero, accelerare
is a Latin verb transitive meaning, roughly, to hasten, to speed up (an object). Something doing the hastening is accelerans, accelerantis
, which eventually yields the English noun accelerant.
But of course it's not consistent. Nothing in English is consistent.
Mathematics is a collective noun, a discipline, practiced by mathematicians. Mathematic is not a word. The adjective is mathematical. Statistics is a collective noun, a discipline, practiced by statisticians. It is also the plural of the noun statistic, a piece of information. The adjective is statistical. Physics is a collective noun, a discipline, practiced by physicists. Physicians are something else, practicing medicine, although they might archaically have been said to practice physic and generally study physiology. Physical is a much more general adjective. Statistic is a noun, physic was a noun, psychiatric is an adjective, ballistic is an adjective, mystic is either but the discipline is mysticism, mathematic isn't a word. Egotistical is an adjective; what is egotistic?
Yeah, I meant to go to bed twenty minutes ago. Can you tell I spend too much time thinking about this stuff?
