indefinite
Lacking clear boundaries
Indefinite describes something without clear limits, boundaries, or precise definition.
An indefinite period of time has no fixed endpoint; indefinite plans lack specific details.
In grammar, the indefinite article a or an introduces nouns that aren't particular or previously identified, unlike the definite article the.
Something indefinite may be vague by nature or deliberately left unspecified: The meeting was postponed indefinitely.
