for an unlimited or unknown time
For a time with no clear end or finish date.
用法パターン：
to [verb] indefinitely
よくある間違い：
Learners sometimes confuse "indefinitely" with "definitely" because the words look similar. "Indefinitely" means there is no fixed end in time, while "definitely" means certainly or without doubt. Also, some learners wrongly use it before a noun (e.g., *"an indefinitely delay"*); it is an adverb and should modify verbs or adjectives (e.g., "postponed indefinitely", "remain indefinitely").
類義語
for an unlimited time (Neutral paraphrase that clearly states the lack of a time limit.)
|
until further notice (Often used in official announcements; suggests no set end, but not necessarily forever.)
|
for the foreseeable future (Implies no planned end yet, but sounds less permanent than 'indefinitely'.)
対義語
temporarily (States clearly that something is only for a short or limited time.)
|
for a limited time (Directly contrasts with the idea of having no fixed time limit.)

to an unlimited degree or extent
To a level or amount with no clear limit.
用法パターン：
to increase [something] indefinitely
よくある間違い：
Learners may use this sense when they only mean "for a long time" or "a lot", even though "indefinitely" suggests the absence of any clear limit. In scientific or mathematical writing, it is important not to confuse "indefinitely" (no fixed limit) with "infinitely" (truly without end in a strict sense).
類義語
limitlessly (Emphasizes the complete lack of limits in amount or degree.)
|
infinitely (Often used in mathematical or formal contexts; sounds stronger and more absolute.)
対義語
finitely (Technical opposite in mathematics and logic, meaning within a fixed limit.)
|
within limits (General-language opposite, stressing that there is some boundary or maximum.)
