IPA: /ɪˈlɪmɪtəbl/
KK: /ɪˈlɪmɪtəbl/
Something that cannot be limited or restricted; it is boundless or infinite.
The universe is often described as illimitable, stretching far beyond what we can see.
Illimitable → It is formed from "in-" (meaning not) and "limitare" (meaning to limit). The word "illimitable" means not able to be limited or boundless.
Think of 'not' ('in-') being able to 'limit' ('limitare') something — that's why illimitable means something that cannot be limited.
