Something that is infinite in nature.
"The universe is often described as being infinite in its vastness and complexity."
In plain English: Infinite means something that has no end and goes on forever without stopping.
"The universe seems to contain infinite possibilities for exploration."
having no limits or boundaries in time or space or extent or magnitude
"the infinite ingenuity of man"
"infinite wealth"
(of verbs) not having tense, person, or number (as a participle or gerund or infinitive)
"infinite verb form"
too numerous to be counted
"countless hours"
"an infinite number of reasons"
"innumerable difficulties"
"the multitudinous seas"
"myriad stars"
Indefinably large, countlessly great; immense.
"The universe seemed infinite to him as he gazed upon the endless stars stretching beyond the horizon."
In plain English: Infinite means having no end or limit at all, so it goes on forever without stopping.
"The number of stars in the universe seems infinite to us."
Usage: Use infinite to describe something without any limit or end, such as an endless supply of patience rather than a specific number like "very many." Do not confuse this with finite concepts when describing quantities that can be counted or measured.
Infinitely many.
"There are infinitely many prime numbers between any two consecutive perfect squares if we consider a sufficiently large range extending to infinity, but strictly speaking, there are infinitely many whole numbers greater than zero."
The word "infinite" comes from Latin infinitus, which combines the prefix meaning "not" with a root related to an end, originally describing something without limits. It entered Middle English through Old French and eventually replaced the native Old English term for endlessness.
