I’m aware of the existence of Infinitive as a verb for (‘to’ + base) but my question is moreso based on the derivative portions of the two words and as how they can be applied to a specific meaning, and do others consider this a logical notion: Where “definitive” can be described as ‘that which can be defined’, or ‘to be done in a definitive manner,’ then would the inverse “Infinitive” be capable of existing as referring to ‘that which cannot be defined’? (Since the infinitive of ‘to+base’/to do something in a manner that is not decidedly definite(?) already exists.

For example, by definition of the parts of ‘definitive‘, molecules would be decidedly definitive by nature(and quantitive nature, which is somewhat the main focus in defining the designative factors of the terminology), where a finite amount of atoms exist, and (typically) abstract subject matter such as numbers would be decidedly infinitive by nature due to there being an infinite quantitive existence (sequentially speaking). Also, would other things exist that would likewise be described as “infinitive”, by this definition

Existence of that which is definite, vs. Existence of that which is not definite(the infinite)

  • The "amount" of atoms is potentially infinite, same as the "amount" of numbers. Of course, only finitely many are realized in nature, but the same is true of numbers. It is also unclear why "definite" should be identified with "finite", this is certainly not how the word is normally used. Natural numbers are a much more "definite" concept than sentient beings. – Conifold Aug 1 at 5:03
  • The suffix "ive" makes an adjective; definitive= which is defined; infinitive= which is not finite, which antonym would be finite (already existing adjective, no need to apply the suffix to another word), not definitive. The rest is quite biased. – RodolfoAP Aug 1 at 5:36
  • Molecules are more likely to be definitive by nature as though the universe is expanding, there lacks information that would designate molecules as infinite if the Big Bang theory insists all matter has a single origin point, this means molecular matter is definite in quantity, as atoms cannot be made from nothing, merely clinging to the form they exist in or changing to apply to forms they can further exist in. But definite in quantity nonetheless, whereas numbers possess no logical ending in quantity as they exist as an abstract construct, where adding 1 to any number furthers the spectrum. – Emero Aug 3 at 17:23
